They both have great lenses, but there is no getting around the fact that one produces a neg 50% bigger. I'm sure that dependent on your technique, you will get some excellent 20 x 16 prints from the Bronica. But I'm equally sure that with the larger neg you'd be operating less "on the edge" and that with some images there would be a difference that you could see. It may be that occasionally that difference would mean the difference between having a great print at the size you want or having to compromise.
