In the past I used to be in love with the winter biome and its trees, but nowadays I only build houses in plains or forests.
I just like biomes that experience weather, and experience often. Basically, I like any biome except for Desert.
But you can still find nice weather in the desert.. I mean, who doesn't like dead ferns and a clear sky? Just kidding, I agree with you, that's why I like the winter biome a lot, snow is cool.
I love the Jungle and Cold Taiga biomes, but I'm also pretty fond of the Flower Forest and Mushroom Island biomes... Basically the only one I find boring and refuse to build in is the Desert, though. It can be a nice place to go if you're looking for cacti for some reason, but other than that, everywhere else is more interesting and looks nicer.
