I probably won't go that far. Some may choose Doom or Wolfenstein or Half-Life as best FPS. I don't play enough FPS to have a fair opinion on the matter. I just have some nostalgia for the game.
Like when the lid of the sarcophagus rises and you talk to the pharaohs head, when the pharaoh is done talking with you and you're quick enough you can jump into the sarcophagus before the lid goes down and get stuck in their. It's not progressive or any secrets or anything,. just a stupid little exploit I found.
Doubt that exploit is in the remakes.
Best is relative.
Best depended on who.
If we are talking about Saturn version and uses GamePro Magazine's score, Exhumed / Powerslave was indeed the best one.
It got perfect score.
Other magazines could give other results though

For me I prefer Wolfenstein 3D due to memories of playing them with my friends on PC,
but that game wasn't released on Saturn (not counting homebrew).
