Genesis, easily. The Genesis was comparable to one of Nintendo's best systems, the SNES. It is also the only Sega system I actually own and play. I tried buying a Dreamcast a couple of times, but they kept breaking down shortly after I bought them. My much older Genesis still plays games just fine and has a much bigger and better library. The Genesis is just plain awesome.
