Neo Geo had multiple processors.  One that was 16-Bits and an audio processor that was 8 Bits I believe.  In that sense, the main game processor was 16-Bit.  You can't just add them up.  If that were the case, the Sega Saturn would have been a 112 Bit system.
My fav games were:
Genesis: Tie between Sonic 2 and Sonic & Knuckles + Sonic 3 locked together.
Honorable mention: Contra Hard Corps and Rocket Knight Adventures
SNES: Super Mario World
honorable mention: Super Metroid and FF4 Hard-Type
Neo Geo: All the King Of Fighters Games (98 and 99 especially)
 (98 and 99 especially)
Honorable Mention: Fatal Fury Series + Last Blade Series.
