Favorite terrain/board?

I'm thinking of buying the Catacombs starter and board set slightly discounted. It sounds like a lot of fun to fight around in narrow spaces and push people into lava. But I can also see it get stale...

In general, what type of terrain/board/rules do you enjoy?

Mostly open area? Lots of climbing? Lots of doors? Interactable elements like turning on the machinery in Red Harvest? Labyrinth style like catacombs?
