Google is my favorite because it's engineered with a lot of new and smart ideas. It's different from other browsers because of its virtualization and its crazy-fast java engine.
Other than that, does anything really set Chrome apart? I don't think so.
Do I have to refer back to IE on a regular/semi-regular basis because Chrome doesn't really support every webpage? Yup.
IE always displays websites properly in the corporate world, but none of the other browsers are supported as much as IE is. It makes me sad also, but it's the truth
The only other browser that has come close to the kind of compatibility that IE has (that I know of) is Maxthon. But after using it as an IE replacement for about a week, I had to give it up (it was crashing more than IE).
Life is sad sometimes.
