The Dr. Gonzo set is currently the only one that's anmorphic. Personally, the image on that set is a bit too soft for my liking, but it's certainly got a nice presentation and comes complete with the commentary from the laserdiscs. (However, the commentary is quite sparse, and segments of the movie during which the commentary plays are included as extras in the TR47 set, on the bonus disc.)

If you look around, there's information threads for nearly all of the sets around. Also, go into your personal preferences and set it to show older topics and then browse back, if there's anything you don't see.
