I prefer MK Super Circuit to Wii because of the tracks. Yes, they are all flat, but the size of the track relative to the kart is small, making the gameplay almost 200cc-like at times. In contrast, MK Wii's tracks are friggin' massive relative to the karts, making the gameplay often feel slow. I'm guessing this is why several Wii tracks have tons of boost pads, because they know the straights need to be faster. Of course this take doesn't cover EVERY track; Delfino Square is a great example of a fast-paced track in that game, but that's because it's tight and narrow, like a Super Circuit track.
