I voted for the M3 over the MP, but it was extremely close. I think the MP has cleaner lines and the chrome is a bit nicer to my eye. The new covering also looks better to me, though it is not as nice in use. But the edge goes to the M3 because of the better, more complete engraving, and the beautiful film type indicator on the back. Those little pictures are much more elegant to me than the simple M6 or M7 style wheel on the back of the MP. They are so close though.
