I used to love IE, but after a while it just gave me so many problems so I've switched to Google Chrome. It definitely loads a lot faster and it's just a better browser altogether.
I'm a Chrome fan, personally. It works, it rarely bugs out. AdBlock is a great plug-in, I highly recommend it. Occasionally it wonks out with some more advanced online applications, and that's when I switch over to Firefox. IE sucks because Microsoft refuses to be compliant with CSS3 standards so a lot of pages come out weird. (As a web designer in training this irks me to no end.)
I have Google Chrome, Firefox, Safari, Opera, Rockmelt, Seamonkey, xombrero, Internet Explorer, and Maxthon. I use Google Chrome the most, though, because of how simple it is.
@ Yayzikens I didn't even know half those existed. x]
I have Firefox on my laptop and Chrome on my desktop computer. I just installed Chrome on the desktop, so I currently have no preference as to which I find more suitable.
