That would simply depend on features of the boards and personal preference. I would also take into account quality control as well as warranty and customer support.

 
Moving to General Hardware (Non-Evga products).

Read the review, you gave no detail on how you want to use these MB - so only generic answer

My --- 2 cents --- avoid ASUS
 
--- they have a habit of killing your CPUs on reboot, occasionally  http://www.overclock.net/t/1561131/5960x-dead/200
 
-- not a risk I was willing to take, so I bought a EVGA X99 Classified

Wait for the EVGA x99 Dark. Newz should be coming soon :)

a man can dream 

Or die of old age waiting

Let me give a detailed description.
 
I'm buying a new rig for security and workstation related work. I was planning on to take the 128GB RAM motherboard but then some said that much memory won't be necessary. I have an interest towards Rampage V extreme but if MSI X99A is better than ASUS then I will go for it. Money is not a constrain until it's worth investing on MSI.
 
Also which board has better features than the other. Please point out so that I can go ahead and buy a rig for myself.

These are gaming, overclocking - MB --- not workstation boards.
 
Which CPU are you going to use?
 
How many GPUs do you plan on using?
What GPU?
 
How many Drives?  What type?
 
Other cards you plan on using?
 
What OS and programs do you need?
 
Air cooled, custom loop or AIO cooling?
 
PSU & case?

GIGABYTE SOC Champion is good board. 
She only have 4 DIMM place but I don't see that as problem at all. 
GIGABYTE have and SOC Force but she cost more. SOC Champion version is 200$ cheaper than Godlike and 150$ than Rampage 5 Extreme.
I think that no reason to normal users pay so much for motherboard. Even Champion is better choice for most people than Force.
But when someone used on ASUS boards than it's hard to change that and than overprice boards ... 
90% of people no reason to pay over 300$ board for X99. Don't even to talk about Z170. Z170 no reason to pay over 250$.
Motherboards for Skylake are most overpriced boards for long time. Companies exactly estimate that people will pay even more for Skylake and completely forgot on cheaper X99 variants only because most customers look on X99 as i7-5960X and nothing else.
In their head is 1000$ CPU or 550$ CPU, 4 memory modules necessary and that's blockade in their heads.  
And they usually finish with 400$ spent on Skylake, 300-400$ on Z170 motherboard and two 8GB modules cost them as four 4GB.
 
X99A MPower, GIGABYTE SOC Champion, ASRock Fatality X99X Killer, ASUS X99A or X99 Sabertooth... no reason to people pay nothing more.
I would never Install i7 on 150$ motherboard. But 200-300$ range depend on chipset absolutely is enough. 
Today more companies pay attention on implementation 20 settings in BIOS... Normal users need only 4-5...
Other options could make difference on some competition in one moment for 0.2% improvements... They are useless for 24h/7. 
No one want to build motherboard instead so many function to pay attention on durability.
Normal overclocking for every day is not expensive.
It's expensive when you pay for settings useless except under LN2, and even than many times no one change some settings, manufacturer recommend even to advanced users to keep on default. 
 
MSI launched and X99 Godlike Carbon... She is really premium product, expensive on first look ...
My first task would be how to custom build silver X99 logo replace Dragon Logo on heasink... and MSI should include some other option in package for customers who don't want to look Dragons or similar... on motherboard.
They lose 10% customers only one similar details... Not only MSI...
 

 
 
ASUS made biggest fail in history with X99 motherboards... I mean on options and what customers could buy if they want ASUS X99 motherboard.
Their X79 series was far far better... Look example ASUS X79 Sabertooth compare to X99 Sabertooth. X79 Saber was something really attractive, than X79 Formula was high end board but affordable for more people, X79 Gene - mATX motherboard with best layout for some mATX Motherboard.
Not as today X99 motherboards no small slots. She had three big PCI-E slots and one PCI-E 4.0. Than two Extreme versions. 

That's not board for normal people... Such configurations could cost up to 50.000$...
Only one DIMM ECC 32GB is 300-350$... and two processors up to 10.000...
That's really expensive stuff for office, 32 or 64GB is nothing for them...
ASUS have Z10PE boards, C612 Express but several PCI-E slots.

Post #10 says it's for a workstation.
 
A pair of these would be reasonable:

Msi not only makes a solid mobo they have great software too.

Maybe you are right, they build nice X99 motherboard series but I would like to stay with ASUS in future.
Rampage V Extreme is nicer than Godlike.

OK she have newer features, M.2 Turbo is up to 32 transfer.
All ASUS X99 boards have max M.2 transfer and I don't know why ASRock and MSI call that Turbo.
Bluetooth 4.1 over 4.0 will not save anybody and all boards for 30$ become USB 3.1 A+C... Z87, Z97, all boards.
Over SATA Express ports or over PCI-E slot.
I'm not special fan of boards with shield as Maximus Formula, Godlike, Sabertooth...
Only board that I think will be nicer than R5E is Black Edition, but side by side R5E look more serious than Godlike...
That's case with all Maximus Extreme and Rampage Extreme boards compare to competition... Hero and Gene are little lower standard. 
MSI launch two early two Godlike boards and what for Broadwell-EP they think to launch third Godlike version?
They should live Carbon version at least for Broadwell-EP... 
ASUS have far better style with color tones on their boards...
look example Maximus VIII Extreme and Matrix Platinum, they are really beatiful color combination. 
Godlike and Twinfroze are funny compare to Maximus VIII Extreme and Matrix Platinum...
 

 
I only could imagine when ASUS transfer same colors on Rampage V Extreme Black Edition...
Only board will look even more powerful because huge socket for Processor and memory slots on both sides.
 
 
 

All customer service are same ASUS, GIGABYTE, MSI, ASRock... same.
GIGABYTE ignore people... example card stop to work they never respond you on RMA request.
Only people look on ASUS as top brand than many place empty than everybody else and because of that they are angry because their technical support is not on same level as design team. Their guys who should design new hardware work under special condition...
They listen music there, look movies, books, everything only with tasks to new idea born.  They draw there, write, like little school... 
I don't look on companies and brands any more who have good technical support and who not...
Some people have better experience with one company, other have worse experience with same. 
After everything what happen with K|NGP|N card motherboard, graphic card, sound card - ASUS, forever. 
That story is finished. 
 

I would suggest you to take a look on GIGABYTE Forum you will be surprised how many people don't get answer on questions at all.
Even now I would not be surprised if their tradition continue... 50-60% questions have 0 replies. 
GIGABYTE is not even shadow of ASUS... I would not be surprised if ASUS sell more motherboards than all companies together, and 50-60% graphic cards, and 70-80% sound cards, and 50% gaming monitors, rest share other companies.
 
PEOPLE SHOULD STOP TO BUY AND SUPPORT INFERIOR COMPANIES BECAUSE "BETTER" TECHNICAL SUPPORT BECAUSE AT THE END WILL HAPPEN WORSE COMBINATION, THEY WILL STAY AND WITHOUT GOOD TECHNICAL SUPPORT AND WITH INFERIOR PRODUCTS.
AMAZON WILL DEAL WITH ASUS ABOUT EVERYTHING PEOPLE ONLY SHOULD ORDER AND BACK AFTER FEW DAYS IF THEY ARE NOT SATISFIED AND CHANGE BRAND OR MODEL. THEY DON'T NEED EVEN TO CONTACT ASUS IF SOMETHING IS NOT RIGHT, NOTHING, FORGET ON REGISTRATION, DEBATE WITH TECHNICAL SUPPORT, ETC... IF THEY ARE SATISFIED THAN IT'S NORMAL TO KEEP, IF SOMETHING NOT WORK, HARDWARE, SOFTWARE, BUG, THEY SHOULD CONTACT AMAZON AND REPLACE OR SEARCH THAN OTHER OPTION. NOTHING WILL GOOD HAPPEN IF PEOPLE CONSTANTLY AVOID SOME BRAND FROM FEAR WHAT IF THEY ARE IN 5% WHO GET FAULT SAMPLES. WHEN NEWEGG NOTICE THAN AMAZON HAVE SEVERAL PERCENT MORE ORDERS THAN THEY WILL DO SAME. 

ASUS support is a joke.
im on my last asus board now,going back to evga.
bought a maximus VII but it had a corrupted motherboard driver disk,could not get online.called asus and offered to pay for a new disk,no can do.

I normally go to the motherboard support site and download all of the latest drivers and save them on a USB flash drive for initial install. The drivers on the supplied disk are usually so outdated they're not worth installing.

me too,but i always load the lan driver so i can go online to download them.
windows drivers would not work.
