I have/use both. Different kind of cameras, different pictures, different approachs.
you cannot use the 7 as if it were a overgrown leica, if that is what you're looking for, unless you're under pretty good light. Anything under 1/30 is not useable in the 7 handholding it, with much less DOF in larger apertures. Said that I love as much my 7 as my m6
