I'd agree for Blur and Sense but I actually like TouchWiz 4.0 quite a bit more than stock Gingerbread. Unfortunately Samsung is the only manufacturer that actually seems interested in using their skin to improve Android.
I hate Blur, it slowed down the droidX to a crawl. However I liked the keyboard because it was one of the first android devices to have multi touch. I like touch wiz, but I like stock the best, especially ICS.
