I like avant because if you want webpages to load faster you can disable things like pictures, sounds, flash animations, active x, scripts and java applets. it also has alot of options that you can turn on and off, like an auto-complete form filler, you can have url alias' like instead of typng https://myspace.com/browser you can type ms. It also opens all of your pages in the same window so your monitor isnt all blocked up with everything.
