The age-old question. I dunno, for me this is a tough one - I had a Super NES as a kid but my best friend down the street had a Genny - so I played tons of Genesis games (but mostly Sonic) over his house. So based on gaming times 'way back when,' I'd have to say tie, since I had so much fun with each. But these days I have to give the nod to the SNES - I just think it has a much deeper catalog, and there are so many games for it that I love. Fire Emblem 4/5, Super Aleste, Mario All-Stars, all the old classic Square games - Secret of Mana, Final Fantasy IV/VI, Super Metroid, Mario Kart, on and on and on. At this point Genesis is mostly nostalgia factor for me. Probably the one Genesis gem that I remember: I got my buddy a copy of 'Mazin Saga' from the bargain bin for his birthday one year... Turned out to be this classic game neither of us could stop playing, great combination of beat-'em-up and big Street Fighter style boss battles at the end of each stage. Awesome.
