I played with both and I like the TM-15 better. They shoot about the same as you might expect, but the TM-15 just felt better in my hands. The trigger pull is a lot smoother, too. It might not bother you, but the TM-7's trigger feels kinda..gritty. Both are really nice guns and you can't go wrong either way.
