Camino 1.0 is out. It's been out for a while, but I just downloaded it today. I've been using this browser, a spinoff from Firefox, optimized for the macosx platform, for almost a year now, and I am delighted about it. It really feels like a osx application, unlike Firefox, and is faster and has more features than Safari. It even looks nicer than Safari (although I guess this is a question of personal taste) :
This browser is somewhat overlook by the osx community, so I'm engaging into some evangelism here. It's been growing a lot since the release of Camino 0.7 (that's when Chimera, got renamed in Camino). If you got OsX, try Camino ! It can be found here. And here is an up-to-date review.
On the other hand, I have been known to change browser often. I like change. So since I switched to macs (2001), I have used Internet Explorer, Mozilla, Omniweb, Chimera, Safari, Firefox, and gave a kick look to Netscape and Opera. My late favorites are, in order of preference, Camino, Safari and Omniweb 5.0.
