Titans Return Rumble vs Masterpiece Rumble.
I must say that after dealing with both. The leg fragility of MP Rumble's and after having all the add ons on TR's Rumble. I find that the TR version has lots more play value than the MP. Of course, the MP is not for heavy playing, but I don't think that the cheaper toy has much to envy over the MP. At least not as far behind as I initially thought.
