i think i rather go with NES because of the sound effects, look at mario brothers (the first one) when mario hits a brick, there that CRACK or BOOM, and when you look at snes, when mario hits a brick, you get crack or boom (kids way) like what most people are looking for, i look for fun factor and sound effects
SNES is good because the mortal kombat 2 in snes is the best in all consoles (closest to arcade!) its just what's up with sound effect, even genisis sounds better
