I would love to try Kolibri, in the screenshots it looks amazing. Tempo is another one I would like to try out.
Agree about Space Harrier and Afterburner, as far as finding those games on cartridge, the 32X versions are the very best you can get!
There are a few games I would have liked to see on the Jaguar, like Star Wars Arcade, I mean it's pretty damn fun and good looking on the 32X. Would have been interesting to see if it could have been even better on the Jaguar.
