lurker's is my favorite. Extremly diverse, well built (crampy but not crampy thanks to trigger_illusionary, thanks!). And I love all the little tricks.
rudl's I haven't finished yet, died on the second room with enforcers because of ammo shortage. :(
Loved the start though with the beautiful rooms. Some textures did look too cartoony for my taste, Quake's palette is quite limiting here.
Trinca's has some great brush/texture-work and space fillers. Lighting was kinda bland. The vorelings are GAH evil!
My map, uhm, I lost my mapping spirit about two weeks before the deadline. I spent a lot of time into texturing and adding "decoration" on the wall.
