A few years back, my sister wanted to get a Baby Taylor for taking to festivals (for workshops) when she was in the process of learning. I went with her to Elderly and I played both for her (and me). There wasn't a huge difference in such a small body, but we both agreed that the BT2 hog had a little better tone, less bright. So, if you have already made the decision to purchase one of the two (and not considering other options), I would chose the BT2. If you are open to something of the same size and a little less expensive to boot, I'd look at the Martin LXK2. It sounds less thin.
