[Background info]
My Moto G is about a year old. Prior to it I had some sort of cheap Samsung Android from a few years ago that was low end even then. My Moto G is up to date, but I find it very frustrating to use often. Often it feels sluggish, the battery doesn't last very well. After 8 hours in Chicago using the GPS intermittently and an auto dimming backlight app, I was down to 13% on the train ride back. The camera is iffy at best. It is capable of taking decent pictures but not what I would call "Good". The screen is also shattered from a fall on a tile floor from about 3 feet.
Even playing around on some of my friend's phones I'm not really a fan of Android anymore. Initially I liked it for the complexity, that I could customize everything and it was so easy to tinker with. More and more as I get older (Now 21, YAY!!), I find I don't really have time to fiddle with it and I spend less time on it, and often it would be great to have a GOOD voice control on it as oftentimes I'm driving while playing music from it, and it would be nice to just say "next" or whatever than have to look at it when I have time at a stoplight.

Right now pretty much the only phone I'm thinking about is the iPhone 6. My girlfriend has a 5C and while staying with her over winter break I used it numerous times, and it is lightning fast. Switching between apps is just sweet. The camera takes very nice pictures on it, and the messaging works really well. Additionally I can still get Google apps for things like maps and email, and if I need Android I have a 7" Kindle Fire HD that is rooted and loaded with Cyanogenmod.
 
To make it really simple...
Reasons I like the iPhone 6:
Lightning fast, good battery life, awesome camera, fast messaging, iMessenger, the screen, the overall size, various accessories and cases, etc.
I'm unsure because I haven't had an iPhone personally before. First I had a blackberry, then 2 Android phones up to my current Moto G. I'm also concerned about buying a $750 (64GB) phone and having it be outdated in a year or so.
 
I don't think I would really like a huge phone, 5"+. This is why I'm not looking at a Note 4, LG G3, or iPhone 6Plus. I already have a tablet that I use for school, and have no need for a massive phone. The 6 is pretty much my ideal size, but I don't want to get tunnel vision and do something stupid. I have Tmobile by the way. Any input is appreciated.

 
Samsung Galaxy S5

Both me and my wife have the LG G3 and it works great! Son has the S4 hates it! Daughter has the S3 likes it

What does he not like about the S4?  The only thing for me that is lacking is it's speaker.

His is constantly freezing up and restarting

I would RMA that then, sounds faulty.  Mine has never frozen up or restarted In the 22 months I've had mine.

The speakers of the HTC One M8 is what I'm jealous of.  If you could combine the speakers of HTC and the Super AM-OLED screen (screen is just gorgeous) made by Samsung, you would have my dream phone.

i just threw a Otterbox on it ,adds some weight but its proven its worth a few times now :)

They also upgraded the headphone jack on the Note 4. The signal is very clean. I'll have to say... The interface refresh from the Note 3 to the Note 4 was pretty nice. It definitely improves the experience on Android.
 
The G3 is actually the same size as the Samsung Galaxy S5, the problem is... It's running a 1440p screen and the GPU is just barely a step up from what supports a 1080p display. Also, the drivers for the display are pretty horrible from what I've seen, nowhere near as clean as the Note 4 display.
 
The Nexus 6 has a curved back, I messed around with it at the store and it's honestly too large and that curved back would drive me crazy since I like to use my phone on flat surfaces a lot. Motorola made the phone as well. I don't know what it is with Motorola and phone camera's, they just can't seem to get something decent out. Their auto focus is horrible and they add a weird yellow tint to all of their pictures.
 
HTC M8 is an excellent phone, but at this time... It's so late into their release and with the M9 showing up in CES 2015, i'd definitely wait for that.
 
Actually... At CES 2015, they also released a few new Asus phones, the Asus ZenFone 2 and Asus ZenFone Zoom with a upgraded camera. You may want to check into those as well and see if they are supported on your carrier.

I have an iPhone 6. Love it. I find the camera to be fantastic ...it's quick. Screen is crystal clear.
 
I will admit it's slippery..get a case immediately.

Would get a Lifeproof or equivalent for it. How do you feel about it compared to the top Android phones?

I've never really liked the Android OS....so being biased I can't answer with an honest review.
 
 

I wish I could just do like a trial of each phone for a day. :( Tough decisions.. I've never been huge on Apple but the 6 has definitely caught my interest.

LG G3. I swore I would never own another LG phone. In December my carrier offered me the phone for free with a 2 year contract and a free case, and on my same cheapo plan. Great phone. I had the S4 as a work phone and that too was excellent.

Amazon has the LG G3 for 0.01$ with a 2 year contract. It looks like a slightly bigger screen with higher resolution than the Galaxy S5 , same processor and the LG G3 has 3 gigs of ram but the s5 seems to be more popular and it is $79 with a 2 year contract. What gives? I like the idea of a bigger screen because I have fat sausage thumbs.  Looks like a good phone. Thanks for the input.

The G3 runs the snapdragon 801 chipset over the S5's 800 chipset. It also has a 1440p screen over the S5's 1080p. The main difference is the stock enterface. I believe the G3 also has wireless charging on the latest models.

I don't game much on the G3 but when I do it seems to run butter smooth. I just fear breaking the glass on the new phones.....so big they break easier I hear. I have a good case though.

I have a Moto X and love it. Its the only phone I have left stock since it just works. Battery lasts a day and a half with moderate to heavy usage, about 3 days with light usage. Its always been quick but yes the camera sucks. Id say its a good choice for people who dont want a huge phone.

I am going with the LG G3. My sister has the S5 and it is pretty darn nice. I really like the 30 minutes underwater part but mostly for my wife but the LG G3 just has a few features and specs that are better. The wireless charging seems almost like more of a pain especially with At&t but maybe I will go that route down the line. I have a buddy with the note 4 and while it's pretty cool, I hate using a stylus and the "touchwiz" interface just wasn't my cup of tea.
