Both are great, but technically, the Megadrive is more powerfull (bigger resolution, and more CPU power).
If no one played Contra:Hard cops on the megadrive, then he should do it now quickly
This is the best action game on the megadrive, and the most incredible action game on any 16 bit machine.
And about music, this boss theme from eswat on the megadrive is great music, a must listen.
