I can't believe that so many posts CAN be made about something like this.
They are not exactly the same, are they? There's a reason they took Haaselblad cameras to space, used them for scientific photography, and that they were so popular in studios. They are good at applications like that. Extremely competent cameras.
Rolleiflex TLRs are of a different kind. They are smooth, light, beautiful devices that work so well for art photography, more casual and relaxed, every day use, away from the tripod.
They are completely different animals. Both very competent, but apples and oranges, and it comes down to shooting technique which suits the user best. Both cameras are capable of extremely high print quality. Mirror vibration has not been an issue in my years with Hasselblad.
