I forgot the title but wasnt there a saturn fps where the pc version wasnt anything to write home about as opposed to the console version
Sounds like Powerslave/Exhumed.
NES gets discussed a lot but the SMS also has a bunch that are arguably better than arcade or computer versions (while still being roughly the same game):
Golvellius - Notably graphically enhanced over the MSX version. It borderlines on being a different game with the layouts, though.
California Games - Better graphics than on C64 although the music isn't as well made. In some ways the Amiga, Genesis, and Lynx versions are more advanced but they either screw up the controls in some events or are missing events entirely.
Choplifter - Faster and smoother controlling than the arcade although downgraded visually.
Montezuma's Revenge - Enhanced graphics and more forgiving jumps. I prefer the art style and physics of the Atari 8-bit original but many consider the SMS version the best.
Wonder Boy in Monster Land - I think the jump control feels better on SMS.
Impossible Mission - More detailed graphics but it's missing some cool voices.
Bubble Bobble - It plays just as good as the arcade and has more content plus password save. But the audio's pretty bad in this port.
Ultima IV - Some dialogue complexity is lost but the core game is intact and the streamlined controls work well. And some prefer that it ditched the first-person segments.
Shinobi - Some prefer the new controls, added life bar, and power ups.
Time Soldiers - Simplified controls but it's a far less frustrating game for difficulty.
