E1M6 (Door to Chthon): I can't really explain why, but the atmosphere really impressed me. When I startup Quake I often choose to play this level first.
All the maps of Episode 3. After replaying Quake with Darkplaces I have to say that I enjoyed this episode the most. It felt really coherent in general regarding design and it had a kind of atmosphere which was even better IMHO than the other episodes.
If I had to choose one map of Episode 3 I would go for E3M3. (Tomb of Terror) E3M2 and E3M4 following close after.
