Cruise for a Corpse or BloodNet -- two classic adventures -- leap to my mind.
Cruise for a Corpse has amazing music on the Amiga version, and while the PC version had 256 colours, it used them really badly (typical case of colours being added), and the wonderful music was... awful!
Likewise BloodNet was better on the A1200. The terrible fight mechanics of the PC version were simplified which made the game much more fun to play (IMO).
I personally always preferred the Secret of Monkey Island's Amiga music.
