Chrome is ugly. Chrome forces tabs on you (the real estate is wasted whether or not you believe in tabs; I don't, I think it's the sign of a failed window manager). Chrome is slow.

I use Chrome every day because all of my work stuff on my work laptop goes in Chrome, and all of my personal stuff goes in Safari, because that's what I like the best and use at home. Separate browsers mean separate session tokens for work vs personal gmail.
