FWIW, I have and use some a 2x3 Century.
It came from a friend of mine who bought it new back in the 60s and "tricked it out" a bit with a 105mm f/3.5 Schneider Xenar in a Linhof shutter(which IIRC is a rebranded Synchro-Compur). Of course lenses are readily swapped, but that's a wonderful standard lens to have on it. Movements are somewhat limited compared to a proper technical camera, but you do get front rise/fall, some front tilt, and front shift. The only major movement missing(unless there's a trick to getting it I'm not aware of, but I don't recall having this one on any of the various Graphic cameras I've had) is front swing.
My friend had the factory side grip for it with an integrated pistol grip, an arrangement that makes it quite handholdable, and of course using the 105mm with the rangefinder properly calibrated it's relatively fast handling. Using the ground glass is a bit of a pain with a rollfilm back, but for anything that uses a Graflok type system that's going to be the case. You can use either Graflex or Mamiya RB67 film backs with it, and have your choice of anything from 645 to 6x9 with those(although my Graflex "23" backs give just a shade over 80mm on the long dimension).
Years ago, I think on the LFF forum or maybe Graflex.org,
@Dan Fromm even suggested to me(in a discussion about Hasselblad wide angles) that a 38mm Biogon on a Century paired with a 6x6 back could be a viable alternative. I forget if he said it would cover larger than 6x6, although I'm pretty sure he said not 6x9-maybe he'll weigh in given that he's in this thread. Now that I have a camera, I have been watching for one on and off. It's certainly an attracive alternative to me compared to the Hasselblad SWC...
