NEX 7 vs EOS M

So through some impatience and some indecision, I now have both a NEX 7 and an EOS M on the way to me. I previously had a NEX 5n and loved it, but sold it to fund some dslr gear for my son. I wanted to get back into the mirrorless, and originally bought the Canon because all of my dslr gear is canon and I throught it would be great to be able to use my EOS lenses and flashes when needed (or to throw the M in the bag as an extra body). The canon gear has been slow arriving, and I saw a great deal on a NEX 7 kit. Now I have to wait and then compare. Has anyone else tried both of these?

Fwiw, I'll have just the 18-55 for the Sony and both the 18-55 and 20mm for the Canon M. I'll also be using my FD 50 macro and 85 1.8 on both if they'll hold up to the higher MP sensor.
