If you wanted Sense UI then why didn't you get an EVO? Personally Sense is eye candy and that's it....I prefer launcher pro or even ADW launcher before Sense. It's a lot of bloatware and is laggy compared to launcher pro or ADW. TouchWiz has been surprisingly good. No complaints thus far....Sorry that you bought a Samsung device when you were looking for an HTC device
......maybe you should return your phone?
