For me, IE is total poo, if i ever accidently use it i keep getting some stack overflow error whatever the feck that means, FF is forever crashing on the odd time i have ever used it, regardless on weather i have got any plugins enabled or not, crash crash crash all the time, so for me there is only one winner, chrome.
I have been using it ever since it first came out and i really cannot fault it, its clean looking, easy to use, very fast, not a resource hog, plus on the very rare occasion anything becomes un responsive you only lose that one tab that went, because each new tab you create is a seperate process, and the only 2 or 3 crashes i have ever had were because flash had died, so not directly chromes fault.
