Trigun (the original) has a good one, which is not just an exoplanet western setup.

Small world but I really liked the pace of world expanding in Yuru Yuri.

The Melancholy of Haruhi Suzumiya, while it’s not a usual world building, I really love its take, because the world building is pretty much psychological here.

I think Basilisk has one of the best world buildings out there. It may not be long but a lot of things happening here fast.
