I tried Chrome but didn't really feel like getting used to the new layout. So I can't say anything bad about it as I haven't given it enough of a chance, but I use Firefox for all my browsing needs. IE, I never use it, but yesterday it found a way to get a rather nasty virus (first one ever on this pc) Which as far as I know I was able to remove myself. I'll know when I reboot my pc anyways. But it killed any connection to internet for IE which oddly was what my Star Trek Online Launcher works off of and I couldn't log in. So went to the options and reset all options to default and IE and my launcher work. So not too shabby for me.
but as far as rating goes, Firefox>Chrome>Safari>IE
