Apples and oranges.

A valid comparison would be the EOS 70D + EF 24mm f/1.4L - even price-wise

Huh? Why is a 6D with 35mm f2 lens not "valid" and a 70D with 24mm f1.4 lens "valid"?

It is just as valid to compare a 6D and 35mm f2 lens to a 70D with 24mm f1.4 lens. Just the 70D combo will be more heavy, and have a more narrow FOV.

Otherwise I could just argue with the Leica M + Summilux 35mm f/1.4 - at smaller dimensions and smaller weight than a full format Canon.

Yes, one can. Why could one not compare a Leica M + 35mm f2 to a Fuji X series with 23mm f1.4? Or a Leica M to a Canon 6D with 35mm f2 lens? All valid comparisons.

I could also throw in the Voigtlander 35mm f/1.2 which has obviously an more pronounced bokeh.

 

It is a question of "good enough". Dietrdeb has obviously found his sweet spot.

You should read my post again, it seems you miss the point (the point being that a 35mm f2 lens on FF does the same thing, and that a 35mm f2 lens is less big and heavy than a 35mm f1.4 lens, which appears to be important to Diertdeb).
