I got a nexus 6 last night-simple things like pinch to zoom and animations tend to stutter, tapping small touch targets in chrome is very hard (iOS has a nice assist there), Firefox freaks out and fails to render HN with nontrivial frequency, etc. Android does seem to support more customization but iOS but iOS's existing features actually work.

I have none of these issues on my Nexus 6. Firefox on Android is rather buggy, but that's not the fault of the OS. A real Firefox on iOS doesn't exist and likely never will other than the Firefox-ish browser they're working on that will be stuck using Mobile Safari for rendering.

I had a Nexus 6 for about 6 months, it's pretty terrible, as you describe. I just bought an LG G4, it's great. No lag, it just works.
