I think FireFox is better. I.E. has improved somewhat but FF is still cleaner, faster loading, faster surf speeds, and more customizable. Oh yeah... and MUCH safer with various blockers and extensions.
I use AdBlock Plus and FlashBlock to cut out 95% of the annoying crap. It's very rare for an banner to get through and I haven't had any popups at all. All the pages I visit load much faster and smoother in FF with just these two extensions. I also have Grease Monkey running custom scripts on a few favorite pages as well.
The themes in FF are much nicer as well. I like the Walnut theme; my browser looks like it's made of wood. Fun! The sidebar addon saves a ton of time as well.
Oh yes and tabs, tabs, tabs. Sure IE has copied the functionality of FF's tabs but they just aren't the same.
Last but not least by a long shot -- since I've been using the more secure FF, I haven't had a virus in a long while. Back when I ran IE I had the antivirus and firewall software running. I'd still pick up a virus every week or two. Now, I'm still running AV and FW but I haven't picked up more than the occasional malware. If I increase security on my cookies I suppose I could cut that out completely.
