Opera, but use Firefox for Quake live and other sites that aren't supported by Opera and Chrome, but most of the time just Opera.
Ditto. I tried to switch to Chrome, but, after screaming at it about how it opened and closed tabs ("WHY ARE YOU SWITCHING TO THAT TAB NOW?!") and the lack of a stop button ("WHY CAN'T I TELL YOU TO STOP? OH GOD, WHY?!"), I switched back with great rapidity. That, and the fact that it used three times the memory of Opera. I also missed gestures ("I'm holding down the right mouse and clicking the left. Why isn't it going back? Oh yeah, Chrome."), a decent feed reader, the Open Closed Tabs shortcut, and a readable history. I still use Chrome for some sites, though.
I use Firefox on my laptop when in college, though. Mostly because its proxy settings are better than Opera 10 Turbo's. So I use the latter when I'm at home.
