Safari, Firefox, Minefield, Internet Explorer, Camino, Chrome  .. have I missed any?
There are a lot of different browsers on the web, but which one do you choose? Personally, I use two. Safari 4 beta and Minefield. A specific cut down, clean version of Firefox.
Which one is better? Who really cares. Which one will do the job? Both. Which one will do the job better? Both.
Details of both are here:

Safari 4 Beta -  http://www.apple.com/safari/download/

Minefield 3.0.8 -  http://www.beatnikpad.com/archives/2009/03/29/firefox

No matter which one you choose. Enjoy.
Warm Regards,
