Safari - but like others have mentioned, it can be a bit clunky at times. I'll load Camino when it gets too slow. It may have something to do with my needing to boost my RAM, but I noticed yesterday that sometimes I can put in a fairly innocuous URL (chase.com), and it will be faster to go to my wife's PC, wake it from sleep, go back into my account, type the URL into the already open FF, and have the page load there than wait for Safari to finish loading. Expect, we have the same amount of RAM in out machines. It's moments like that when I get mad a Safari. But normally, no problem and I'm happy.
