I've kept beardies before and would keep one again in a heart beat!!! Very cool!!! Eat a lot though and have stinky poo - lol. I've never kept a BTS before but another one I would keep without a second thought. If it were me and both were in front of me I would probably go BTS because I have never had one before BUT depending on the bear die I had to choose from it could be a VERY tough choice!!!
