Both of them!! Bps are great. Tubs set up in a rack, easy to maintain, doesn't take up much room. For the most part their temperments are sweet and docile, they are like the lap dog of snakes. They come in many pretty morphs to choose from. Boas, are great too. We recently got one, and he is the coolest snake. He is in my top 3, him and two of my balls tied for favorite snake. He is also very sweet. However totally different experience. He is inquisitive and very curious about everything. He cruises around and checks EVERYTHING out. He doesn't sit still much, but not crazy like a corn snake. Reason we only have one boa, space. I couldn't pick just one either.
