I have both, and while I like the concept of the MB handle, and it is pretty comfortable overall, for me the front finger groove is a bit too fat...if it was cut a little deeper it would feel more secure.
I do like how the MB has the exposed tang pommel for hammering. Always thought the TM and Recon Scout should have something like that.
The blade thickness in the pics looks the same, but the published specs are 5/16" (7.9mm) for the TM, and 7.4mm for the MB.
