I really like the Lost Caverns of Tsojcanth. It was wickedly deadly.

TSR? I'd have to say The Ghost Tower of Inverness. Amazing traps, use of a lot of the "new" (back then) monster from the (back then) new Monster manual. If you total up the XP for monsters and money it just about brings 4 fighter up a level.
Judges Guild? Caverns of Thracia
