Amiga closer to the arcade??
The arcade isn't bright, it's got gray muted colors like the megadrive, and almost all other system 16 games.
Also the Amiga is missing a lot of animation frames, has lower framerate, and sprites are redrawn instead of ripped from the arcade board like the mega drive. Controls are also off, for example by pressing forward while attacking you can execute a lot more slashes then you are supposed to.
Not that the amiga conversion is crap, it was a good amiga game. But like most arcade conversions, the megadrive/genesis was closer to the original.
