anybody using geforce experience if so why if not why?

Ye I only really use it to do quick and easy driver updates, aside from that I find it annoying.  If I'm ever recording game clips these days I'm using Windows + G.

or sometimes geforce news and mirroring your desktop to a phone :)
 

I use it for the initial/quick game settings, mainly. Their per-game optimizations are a good starting point for really tweaking the per-game settings, or you can even leave them as-is, depending upon how lazy you are.
I've also been enjoying the Ansel/photo modes as well as the performance metrics and automated OCs lately. 
I really don't see any features as "bloatware". I don't see how it can even follow the very definition of the word, personally.
I've measured it's overall system impact many times over the years, especially when specifically testing it, and it's quite negligible on any systems I've tested it on.
Of course, one big system hit is having multiple overlays active in-game (GFE, Steam, Discord, Origin, etc.), so minimizing the number of them active is a must.

I use it at times. No complaints, fairly user friendly

Yeah, it's came a long way since it was first introduced and some bugs got worked out..Works good for me.

I've never found a need for it. Anything I need to do I can do without it. I'm in the camp that it's bloat.

Same as most of the people here. I just do the minimal driver installation as I have never seen a huge difference with gforce experience installed and like to limit tasks running in the background.
