If quantitative tests were useless, Leica and Zeiss would not publish MTF and distortion charts. But they do. Full stop.
I thought DxO revenues came from DxO Optics Pro raw processing software and a series of specialzed film simultion plug ins. If I remember correctly the DxOMark web site is a means to promote the technical excellence of DxO Optics Pro.
The camera evaluations they publish are essentially derivative measurements thay already make for the R&D conducted in support of DxO Optics Pro. They also have data for lenses.
A few years ago I discovered that DxO Optics Pro outperformed ACR for the DSLR/lens combination I used professionally. In my case the improvements were not practical because my workflow demanded overnight image delivery. Speed and convenience are more important to my clients than a 5-10% improvement in IQ.
I am not motivated to defend DxO nor am I interested in annoying Leica owners. At the same time it is relevant to state that every single method DxO uses is completely documented in mathematical detail. I personally can't see how DxO's results are not objective.
While I usually detest automobile/camera analogies, all DxOMark's data measures is the signal-to-noise ratio of the sensor to raw file data flow. Of course S/N is critically related to dynamic range and bit depth. This is similar to only evaluating the overall performance of sports cars' drivetrains. Of course these tests don't completely characterize any camera or lens. They just objectively measure one critical component of the complicated mixture of objective and subjective factors that comprise the whole of the camera.
If I used digital Leica Ms, I would point of that careful optimization of exposure is typically more important than the technical potential of the camera's S/N. The large number of cameras with higher S/N than the Leica CCD sensors rarely function at their full potential because sub-optimal exposure is the norm Convenience trumps evaluation and thinking about exposure. In general photographers tend to place more faith in the camera automation than their own experience and ability to evaluate and optimize exposure.
Finally, DxO will soon test the new Leica CMOS sensor. Let's suppose this system has the best S/N of any camera evaluated by DxO. Does this mean these results would be silly, unimportant and unauthentic? Should camera buyers ignore those results too?
Most sensors of similar size and generation have similar performance in the field. ISO has indisputably improved, and the effects of antialiasing filters are, for real-world use, exaggerated -- often wildly so.
Far more important than using a specific sensor or lens are careful focus and exposure. A Pentax K5 (first generation) or Nikon D7000 can destroy the IQ of an M9 with a $4000 lens under the right conditions. Under other conditions, the M9 will be better.
The trick is to learn your gear and learn how to exploit its strengths. Always has been, always will be.
The magic bullet is not equipment. It is technique.
5. Leica is kind of a snobby brand so people love to see them bashed.
6. STOP ACTING LIKE PEOPLE WHO USE DSLRs ARE INFERIOR PHOTOGRAPHERS!
Self-esteem is not self-respect.
An interesting assertion, but it is both unsupported and tangential to the present discussion.
It does indeed help.
thanks for clarifying.
As an academic, I run up against this problem reasonably often. I find it useful to say up front when I'm using plain language in a technical sense.
Highlight 1: Why? A lot of them are. Otherwise they'd use Leicas, 11x14 inch Canhams, or whatever other camera is best for the job, rather than whatever's expensive, idiot-proof and heavily advertised.. . . 6. STOP ACTING LIKE PEOPLE WHO USE DSLRs ARE INFERIOR PHOTOGRAPHERS! Everybody has a different workflow that they like. Leica only makes one type of camera without a Program mode, and I really don't see what the big deal is. An F100 is absolutely capable of being operated as manually as an MP.
Point 7 is a lot like point 1. Tests like these, and camera reviews, and internet forum posts, or the opinion of anybody in the world have very little to do with your photography. Grab a camera you like and make pictures you like. The only thing that really matters in art and photography is taste. Get killer taste and it will take you further than any lens, sensor, or technique.

Highlight 2: Only with difficulty.

You realize that an el-cheapo Nikkor 50 1.8 surpasses any old Leica lens which are known for their "magic" while the Nikkor has "aberations".
There's a limit to how "magical" the Leica lenses can be. In this digital age, the sensor really holds it important place.
