Cornsnake owner here. Full disclosure, I've never owned a BP.
They are docile, beautiful, graceful, athletic - you can watch yours climb a corner up a vertical wall if there is anything at all to grip. They are out a bit more than is described for BP's. Mine is an easy feeder. They rarely just "sit" with you. They tend to always be exploring when out.
I really don't think you can go wrong with one. I would have a few more if space wasn't an issue.
