The Mega Drive was faster. I think that things like Gunstar Heroes would be much worse on the SNES. All that shit happening at once on the screen would probably really slow down the game, but I could be worse.
Other than that... some Genesis games look and/or sound weird, it's hard to explain. SNES games are cleaner, but Genesis was... "older"? I don't know, they have that characteristic Mega Drive feeling (I immediately think of Kid Chameleon).
