The image quality of MF and the affordable equipment is very nice. I'm happy with only 12 shots per roll too (in 6x6 format) In the pre-digital days, I drooled over MF equipment while using 35mm gear. Now the equipment is affordable, image quality good, etc... It's a good time to enjoy MF. I rarely use my 35mm gear either. I pulled the batteries from it so they wouldn't corrode in the 35mm camera.
I do LF as well, not so much for the image quality but so I can use old lenses and old styles and have big negatives for contact printing, alt process, etc...
I like LF as well as MF and alternate back and forth depending on what I'm after for results. If I want 1950's looking results, MF TLR does well. If I want hundred year ago pictorialism look or thin DOF or crazy nice portraits, LF is hard to beat.
