Anyone have recommendations on map packs for DOOM 1? Conversions you enjoy?

And if anyone wants to chat: I just finished my very first “casual” playthrough of DOOM ep 1-4 (haven’t touched Sigil yet), and while I loved the first couple episodes, it felt like it lost momentum towards the end. Instead of intuitive level design they kinda just throw everything they can at the player. I missed the secrets you could “figure out” vs the “spam the Use button against every wall” type. Is it just me? Does DOOM II continue that trend?
