Chrome does feel faster to me; I remember someone here saying that was because of some kind of procedural loading shenanigans or something.
But the main hook for me is how websites look. I do a lot of reading on the browser, and fonts on Chrome always look better than on Firefox. I would switch to Firefox in a heartbeat if only things started looking the same on it.
I often hear that claim, but for me it was always the opposite. Firefox being fast while Chrome being a slow monster and memory hog. Also when I was using an RPi2b full-time, Firefox was working even though sometimes annoying, while Chrome was a no-go and would led to the OS being unusable.
