I've been using IE, Chrome and Firefox the most. Internet Explorer isn't that bad. Firefox and Chrome are just alot better. They are faster, has more features, the look better and you can get alot of very cool addons. I personally prefer Firefox over all other browsers because you can customise it the most of all browsers, it has more features than chrome and it has the highest amount of downloadable addons of all browsers. Chrome is like 0.2 seconds faster though, but I dont think that means anything. Also, Chrome gives alot of weird errors.
But Internet Explorer isn't really a very good browser. The only things it's good for is security and lag. It's actually a pretty secure browser, but it is slow and imo ugly. I'd say, go for Firefox if you like to customize your themes and get cool addons and get Chrome if you doesn't care for anything else than speed.
