Without the need for another browser war, I'd just like to mention that for me the combination of Safari + the excellent SafariStand plugin works perfectly. I keep Camino (based on Firefox engine) for compatibility issues, that Safari occasionally experiences. Get SafariStand here.
That's what I'm using at the moment too. I like that I can have add-ons (google notebook and adblock plus, mostly).
I tried Camino but it's way behind FF3 and, like FF2 doesn't render some languages properly. (Russian buttons come up as ????? in FF2/Camino.) The beta of FF3 has been fairly stable for me (third beta release).
