I prefer Chrome for sure. It full screens video properly (which I need to automatically trigger turning off f.lux), it seemed faster, it does spell checking of form fields.
I'm sticking with Firefox though as these features aren't much of a hindrance compared to the increasingly shitty behaviour of Google, and one benefit is that my Macbook Pro (2014, max spec), doesn't run out of resources and stop responding anywhere near as often as it used to do.
