I have both versions of Rodea TSS, they came together in a set. I tried the Wii U version for a bit and thought it was alright but I never have tried the Wii game. I've heard the same thing though, that the Wii game is much better.
One I can think of is BC Racers. It's on the Sega CD, 32X, and 3DO. The 32X and 3DO versions should be better as the hardware is more powerful but the Sega CD game is actually the best one.
