Which systems FELT the most powerful at the time (and why)

[Leynos]

SEGA Game Gear. When I got older I learned it was a portable Master System. As a kid it seemed almost as good as a Genesis. Mortal Kombat and Sonic looked good on it. Of course Nomad came out in 1995 and literally was a portable Genesis but Game Gear in 1991 next to the 2 year old Game Boy looked like a massive leap. Just sucks about the battery life.
