I must say that I am very impressed by Samsung's live wallpapers. I really love the ocean waves one. With their live wallpapers, I don't have to go into the market to find ones that are actually quite good to put on the phone. The ocean waves one really shows off the colors of the phone. I am also quite impressed by the speed of the phone with live wallpapers active. The processor can handle it pretty well. There is of course going to be some sluggishness but definitely nothing bad.
