The 16-bit SEGA Mega Drive version came from Sega's main development team and offers smooth scrolling, wider levels built around high speed, and elaborate music from the Yamaha FM chip. The 8-bit version for the SEGA Master System and Game Gear was made by a different studio (Aspect) and is effectively a different game: the levels are redesigned and shorter, the color palette is more limited, and scrolling doesn't reach the same smoothness due to weaker hardware. The music and sound effects are simpler too, since the 8-bit chip lacks the Mega Drive's FM synthesis capacity. Anyone wanting Sonic's speed at full force should reach for the Mega Drive version; the 8-bit one is more of a period curiosity.
