Which Internet Browser is the best?

There are many internet browsers out there and the most popular being Internet Explorer, Mozilla FireFox, Google Chrome and Safari, each one focusing on their own aspects, but which one covers them all evenly.  

Safari focuses on speed, Chrome focuses on ease of use and security, Internet explorer focuses on help and support and Mozilla FireFox on feature set, ease of use, security and appearance. Personally I prefer Google Chrome but everyone has their own opinion.
