Hmm, tricky. There are plenty of buildings I like having, but haven't figured out what to do with them yet. Like the pet store. It's nice to have for many reasons, but right now it's sitting by the beach because I'm just not sure what it goes with yet. But that doesn't really qualify it as my least favorite building.
I would say the King Homer tower, because it looks like a building and takes up space like a building, but it's classified as a decoration. It lives in my inventory.
Most favorite? Hmmm. I guess I'll go with the Buddhist temple, because I find it very aesthetically pleasing.
