Good question. For me; a close choice between the Minolta X-700 with the MD-1 Motor Drive that "just fits my hand," or one of the venerable Minolta SR-T 102 that has everything that I need in a mechanical camera.
Yes, I do have others. There are also Nikon F and F2. There are several other Minoltas, including RF. There is the 2.25 Square. There is even a 4 by 5, but you asked about my favorite. This supplemental information is provided to show that there is indeed a choice to be made.
