Well, you can add me to the list! I have never found the Color-Skopars particularly sharp on any of may Voigt folders, and I had several of them (Vito, Perkeo, Bessa I, Bessa II ...), rather disappointing compared to the Agfa Solinars I have had and still have (again from 35mm all the way to 6x9). And, despite what some people say, of course both of them are not even in the same league as the results you would get from a modern camera/lens like the mentioned Horseman field cameras or the Fuji MF rangefinders.
IMO, a 6x9 folder ist more or less a "one trick pony", you get pocketability and pay in the form of a endless list of trade-offs. And one has to realize that for the money some people pay for a Bessa II or a Zeiss folder, they could easily get a Fuji 690 rangefinder, OR even a complete set of Horseman VH field camera with lense(s) and back(s), which of course is a much more capable and far more versatile tool and is at the same time neither heavier nor more bulky than a RB67.
To the OP, he should make up his mind what kind of photography he is after. If he is after a relatively light, quick to use camera for hand held casual street shooting or hand held shooting of landscapes, a modern RF (Fuji 690 type) will serve him best. If he wants to work from a tripod for landscapes, cityscapes, table top, portrait ... and enjoy the benefit of camera movements ... a versatile field camera like the mentioned Horseman or a Linhof baby Technika are the preferrable tools.
