The dioramas are probably the worst IMO, the temples, huts and spirals are just puzzles, easy safe loot once you solve them. The maze is pretty easy too once you have Aggro Mask II so you can't aggro the pigmen, then it's just one blaze spawner to deal with, good armour and a solid weapon handles that, and the tight conditions help stop them getting to range.
The diorama admittedly is pretty easy with good flight and armour, moves to a little better than the maze at that point, and the ghast spawner can be super useful.
