While Dish may be better then Charter in regards to UI; I have to say after spending two weeks at my uncles house for Christmas vacation last year, I am so glad I have DIRECTV. I found the dish guide insane. The graphics looked like they were out of 2002. And since I'm being nit-picky... i found the Dish remote stiff and unresponsive. I made all these judgements based on my experience with DIRECTV. While I'm probably paying more, I will gladly pay it when I have top notch equipment, High quality UI's and a huge selection of channels. The only downside I can think of with DIRECTV has only recently developed and that's the ATT/DIRECTV buyout. That whole thing has me nervous as hell. Well just wanted to add my 2 cents. I'll go back to my side of the playground now.
PS. After that visit, I was able to talk my uncle into switching and he's extremely happy with DTV.
