Just the first 1. Mortal Kombat 2 and 3 were uncensored and much better than the genesis version.

MK1 looked better on the snes but indeed had censored blood and fatalities.

The Legend of Zelda: A Link to the Past gives it to the SNES for me. Plus it had the Mario's, Super Metroid, Contra III: The Alien Wars, Final Fight, Street Fighter II, etc... I definitely owned both though back in the day.

Sega Genesis.

I loved playing the sports games on Sega. And then when you add Streets of Rage, the decision was made.

The Super Nintendo Entertainment System gets my vote, hands down. In my opinion, it had the better games, as well as the better controls. I mean, who didn't love the Donkey Kong Country games, or the Mario games/spinoffs? You also got the AMAZING Legend of Zelda: A Link to the Past and Chrono Trigger. No contest.
