Well, Thierry did qualify his answer with "depending on what you are shooting"
When you read a forum such as this one, you don't get the representation and variety of photographers that people like Steve, Yaya, or Thierry have had to deal with. This includes a hell of a lot of still life studios who shoot with view cameras every single day. I'm a still life photographer and I don't use DSLRs or Medium format. I use Sinar view cameras with a digital back attached. I would not use anything else, too many compromises.
I like to use movements to control focus, perspective, alignment, etc. You simply can't do this properly and effectively with the same flexibility of a view camera/back. And don't tell me you can correct with Photoshop, you can't and I don't want to, I want to shoot like a photographer, not spend time afterwards trying to create something that just happens so naturally (and for real) when you know how to use a view camera.
From my own experience, an older square multi-shot back attached to a view camera will give you a better working solution than a DSLR or medium format in most cases if you are a still life photographer. And not all still life photographers shoot food photography.
However, if shooting people, I personally prefer to use my 5dMKII, and I don't like medium format for this. I've never really liked medium format much anyway.
Maybe still life photographers are a misrepresented minority here, but there are still a lot of us around for whom a DSLR is not a viable solution.
