OS X: Safari or Firefox
For as long as I have been using OS X, about 4 years, I have always used Safari. I never had many complaints with the browser and it is very fast! Recently I have been annoyed with Safari not rendering certain pages correctly. I know that Safari is W3C compliant and the real issue is the code used on the page in question, but still it can be annoying.
Many of my friends are suggesting Firefox. While I am no stranger to Firefox on the PC or even *nix (FreeBSD, Linux) I have yet to try it on OS X ...
