I use IE8 almost exclusively and it looks fine to me. I'll mention anything if I notice it.
My users have mostly IE so it's best for me to stick with that. My group is not computer savvy.
I did make the decision to switch to Firefox in January, and I got a Firefox virus the exact same week. It was the first time that Firefox had been hit by a vulnerability so it was extremely ironic that this happened. I got that horrid bug that replaces all the search engine links with advertising links. That was a TERRIBLE thing to get rid of.
So I'm using IE8 and y'all better not be too quick to brag about Firefox. :)
