My experiences in browser world
InternetExplorer - Kids, just say no to IE, mkay?
The worst browser I've met. When I got my first computer 4+ years ago I almost immediately changed browser. Back then I didnt know about security holes in IE, but the browser itself was so poor that I dumped it and switched to NeoPlanet which my friend was using.
NeoPlanet Browser -
http://www.neoplanet.com/IE based browser. Started using this as my friend used it too, was basicly "prettier IE". Anyway, dumbed NeoPlanet very soon as I discovered Opera.
Opera -
http://www.opera.com/I used Opera for a long time but around version 6.50 switched to Firefox, which was just renamed to Firefox from Firebird. Opera was pretty good browser, I havent used latest versions but Opera would be my second choise now.
Firefox -
http://www.mozilla.org/I've been using FireFox since version 0.8.0. The most advanced browser I've met, slighly better standard support than Opera, but regular user wont notice difference. Very customizable, lots of extensions and settings to tweak. User has the power over this browser.
Summary:If user is looking for a basic browser without fancy features, bare Firefox without extensions is good for that. If user is looking for advanced browser but doesnt know very much how to tweak one, Opera would be my choise. If user is looking for advanced browser and knows how to tweak software, I would recommend Firefox.
Other browsers I've seen:Konqueror -
http://www.konqueror.org/Browser that is integrated to KDE, Linux. I havent used much. I think latest version passes Acid2 test which Firefox and Opera barely fails and InternetExplorer is total failure in that test. Acid2 tests CSS skills of browser.

Dillo -
http://www.dillo.org/This little fellow is common browser in tiny Linux system. It is only 350KB, so fits in a floppy easily.
K-Meleon -
http://kmeleon.sourceforge.net/Gecko (Mozilla render engine) based browser which I tested long time ago.
