Edit: Just sayin', when you want to rip the Google out of Chrome, why not go for something that suits you better? With less unwanted features that please the company not the user.
The only annoying thing is a lack of sync, but I also download chrome for when I need to look through my desktop history or whatever. If you use a password manager that's pretty much the only thing you lose
The replacement for Firefox for Android is coming along nicely but it's nowhere near completion yet.
Improving stuff like this makes Chrome somewhat bearable until Firefox can match Chrome in performance.
Also, it's a lot easier to de-clutterify the main default screen and set a simple about:blank as the home page without having to dig into about:config (chrome://flags) - Chrome loves to hide things from you and force their world view (NTP), Firefox makes it all simple to disable and live a clutter-free mobile life. $0.02 USD :) (I just counted - I have to go disable 5 NTP chrome://flags to de-clutter the home page, whereas Firefox I just use standard menu choices to set a default home page)
