Stock Android doesn't bury stuff in a million different locations and their settings menu couldn't be simpler. Open Quick Tiles -Settings... there's everything logically laid out for you. I've been using it for months, and the consensus industry wide is that the 'stock' Android on the Nexus 5 is the most polished and refined version out there... and I don't think I've ever read "not intuitive" in any review or breakdown.
I apologize for the testiness.... but I get a little aggravated when I see the "just not polished" tag get thrown out there..... it's just a dated viewpoint from my point of view and not based on how things are now.
It is unquestionably the most intuitive thusfar. That's not a point to be argued at all. It still isn't as intuitive as other modern OSes or even as much so as some of the more dated OSes like MeeGo. People aren't going to harp on it from a review perspective because they're coming from Android being a chore to use to being usable and it is taking great strides in the right direction. There are MANY areas where Android is lightyears ahead of the competition. This just isn't one of them.
