SNES games look and play really great on old CRTs. That's the version I'd go for, I've got a SNES hooked up right now. The N64 on the other hand is always better emulated. It just looks SO grainy and blurry that most games are like unplayable now. I tried to play Majora's Mask for the first time on it a few years ago and couldn't deal with it, but on the Wii Virutal Console it was fantastic! Especially with component cables and all that.
