I would (and I did) go for a Leica M6. I am sure the G2 is a fantastic camera, and was an engineering marvel for its time, but I just can't get along with late 80s - early 90s electronic gadgets. They feel like "retarded digital" to me. Mushy buttons, rough sounding electric motors, dumb autofocus, crude LCDs and LEDs. All of these things have gotten dramatically better over time. Meanwhile, fine mechanical devices like the M6, have not improved and, some would say, have gotten rare and more appreciated with time. In other words, a Leica still delivers best-in-class manual camera user experience while the G2 automation has been eclipsed by digital cameras.
