Some pro shops and bowling centers have copies of BTM and BJI available for their customers to browse. See if you can find one of those places to compare both magazines before you make your decision.
Edited to add:
Like others have already said, both magazines offer different bowling perspectives and interesting articles, but if I had to just choose one, I would go with BTM.
