wads/megawads with a large variety of bestiary monsters

[punnyone]

I was wondering which wads, or megawads feature a large variety of monsters from the doom bestiary.

Besides well known ones like KDIZD, UTNT, and Zpack, can anyone lead me to any ones I haven't mentioned?

zen dynamics has new monsters, and some of neon's maps if you can find previous threads in this forum. happy time circus had new monsters too (if that was the right name, I forget)

I suppose Demon Eclipse counts as one of the well-known ones. The ZDoom Community Map is also worth a look.
