> Firefox's sync for example doesn't sync extension settings, search engines and it fails on Android multiple times per day

Chrome for Android doesn't support extensions at all, so I'm a bit confused as to how that's a better experience for you.

It's not a difficult puzzle: I find an always working and worry-free sync of open tabs more important than having extensions on mobile. I'd like to have those too, but right now I have to choose.
