Browser Confusion...?

For years I have used Internet Explorer...That is...until I discovered Mozilla's Firefox,which seemed to be 100 times faster than IE,not to mention really COOL....but NOW I keep seeing all these neat-o things that the browser Flock does,and I'm not sure which one really IS the best.No doubt Firefox is waaaaay faster than IE,but there are so many really different things that go with Flock,that I'm just not sure which is the best one to go with.It's definately time to wipe out my system and restore it back to factory settings,or better yet BUY A NEW ONE.But tons of traffic tickets and car repairs are putting a hold on a new computer(dammit)...anyways,what browser do YOU use?
