Here’s my tier list of biomes to build in:

1. Plains, best looking biome and you can farm the late game crops there, plus easy blackmetal transportation, in terms of aesthetics this one has a major edge

2. Mountains, very infrequent raids aside from a few skeleton surprises, barely any mobs that do a lot of structure damage, probably the safest biome for a base

3. Meadows, looks nice and only raids will threaten your base, easy starting biome

4. Black Forest, has lots of wood but trolls and the uneven ground make it hard to establish a good base, meadows are just better in every way

5. Swamp, terrible, always rains, water everywhere, tons of mobs that deal significant structural damage, super dark, uncuttable trees everywhere limiting space

In my world my two largest bases are in the plains and mountains, my largest in the mountains because I found a really cool location, and a farm base in the plains. My original meadows base now only serves as a graveyard to hold my old portals that still find use and as an onion farm. Never even attempted to build in the other 2 biomes.
