I use Avant because this 2 reasons:
[*] It uses the IE engine, which means that most pages in the web will displayed as they were designed (most pages are designed to be well viewed with IE, and their webmasters forget about other browsers). Also, there are pages (like
http://windowsupdate.microsoft.com ) that only can be viewed with a IE compatible browser
[*]It has tabs and helps me in having all the opened pages clean and tidy. When I'm at the uni, I use netscape instead of IE just for this reason. Netscape has tabs and IE doen't. It's a feature I like very much.
[*]There are some other reasons more (mouse clicks, etc...), but they aren't as important as those 2 ones.
