I love the tropical biome because the colors are very vibrant, and I love the tropical dirt color and texture. My next pick would be temperate because it's kind of the middle of everything - lots of animals from colder to warmer climates can thrive in open spaces with minor adjustments, of course. I wish the tundra biome would have been a bit more friendlier to build in. You can't really see anything because as soon as you put it down, it gets covered in snow. You can't even see paths properly, and it's just totally unrealistic to put heaters everywhere just so you can build. I think I would pick tundra more often if it wasn't so hard to look at and build in.
I wish we could mix and match terrain paints with biomes, and I also agree with posters who have said we should be able to pick backgrounds.
