Thanks for all the reactions, to keep things short, is it fair to say that there is difference in low lIght IQ, but it’s wrong te expect a high improvement when using an comparable aperture.

The 6D has a very noticeable improvement over the 5D2 and the 5D in high ISO noise.

Lets compare a 30mm f/1.4 on my 77D cropsenor with a 50mm stopped down to f/2.2 on a 6D (30x1.6=48 and 1.4x1.6=2.2) am I correct when saying, that because of the double in size photosites on the 6D (24,2/20,2x1.6=1.9), you can expect one stop extra sensitivity?

The size of the photosites is a secondary factor. In that case, you get more or less the same noise but a noticeably better resolution (some of it will be lost in the noise).

Furthermore you have the abiltity to use faster primes, lets say a 50mm f/1.4 which also gives you an extra stop?

Actually, this is the factor giving you less noise, at the expense of a shallower DOF.
