Well you guys really didn't cite any specifics

But that's okay, I'm sure glad we have the choice.
I'd argue against the boring complaint, it just gives a cleaner slate to build your device from. I don't do the whole xposed thing, but nowadays you can pretty much make stock android look and do whatever you want without romming or taking the skin's performance hit. Indeed it takes more work than taking the skin route, but that would make it less boring eh?
Of course that's not everyone's cup of tea, and I enjoy the raw experience with my own small tweaks, so I dont need to put forth much effort to get the device where I want it to be
Then there's also the fact that there's no carrier interference or control over the device but I digress
