What´s your favourite battlefield biome in 30K/40K?

So the new HH 3.0 teaser mentioned Isstvan 5 to be the next conflict set in the Horus Heresy. I am less thrilled for that because imo the environment of that place is just too depressing and not fun to look at because it consists of either grey or black sands/debris. And this train of thought led to the following question: 

 

What´s your favourite battlefield biome in 30K/40K?

For my own gaming table I like death worlds with big woods and overgrown ruins. It's a bit sad, that 10th doesn't have much to offer for special terrain or neutral monsters on the battlefield. 

 

But I also like city fights, especially those depictions of giant, larger-than-life Hive Cities with ridicoulus gothic architecture and multiple levels to fight on. Would be a nightmare to model and play on, but I like the thought of such a battlefield.

I generally prefer city fight biomes or quite industrial type locations. Partly because I just like the look of them but also because they tend to be the easiest ones to add a bit of verticality to games.
