One nice thing with open source is that often you don't have to use a "vanilla" version of a given system. I'm using Ubuntu but I view Unity and Gnome-Shell as brain-dead, tablet oriented interfaces but fortunately, I can use Ubuntu Mate and don't have to deal with this stuff at all.

I mostly like where Firefox is going, I like it's multiple identity tabs and it's general look. But it might help Mozilla to work out various ways to make sufficiently "skinnable" that someone else could maintain a Chrome-like version for all those people who like whatever it is about Chrome that's cool.
