Has to be the Nomad. Yeah, I own a PSP and have homebrewed it thoroughly and it's pretty great, but for the early nineties, the Nomad was amazing. It was like being able to carry a Genesis around with you. It had a second controller port. Also an AV out, so you could hook it up to a TV. Not that you would need to, the screens display is just as good, and well backlit. If only Sega could market their game systems as well as they could design them...
