I have a Mamiya 7, and recently bought a Leica M4P. I love the Mamiya, the prints I've made from the negatives enlarge beautifully. I shoot a lot of portraits of children, and found the medium format a little too slow, and with only ten frames per roll, I had to stop too frequently to change the film. So I figured, I could maybe get similar optics with a 35mm rangefinder, and indeed I do. I am amazed at the negatives I've gotten from the Leica, and they enlarge very well. I think with these two cameras I have the best of both worlds, and can use each for the type of shooting that suits it best. There are examples from both cameras in my gallery, as well as from a Nikon F100, which I find I'm using less and less!
