Maybe the better way to phrase my question is to ask: "Given that you use Medium Format - When and Why would you choose a TLR over an SLR/RF?"
Where noise is an issue, the TLR is silent.
For portraiture, there is no lag for a mirror to get out of the way and you can see the subject's expression at the instant the shutter fires, and know whether you got the shot.
The smaller size and waist level finder is often less intimidating and more discreet.
It can be hand held, or braced against a table or other object, to allow slower shutter speed than an SLR.
It's lighter and easier to carry all day.
