Yes, it does seem to deliver very good noise behaviour, esp for such a high density design. I downloaded some raws just this last week and I was very impressed, not just with the amount of noise, but also its quality - it looks fine-grained and more like old-style film grain than digital noise.For me the most interesting thing about the sensor as implemented in the Leica SL3 is the ISO capability. One reviewer mentioned that he could see no difference between shooting at 1600 ISO or shooting at 100 ISO and bumping the exposure slider 4 stops in Lightroom. In theory this is how it should be, but for most cameras it isn't.
A more forgiving sensor with greater dynamic range and bit depth is more important to me at this stage than MP. As Paul said earlier - 40mp is plenty.
However, I think in absolute terms, there's still more noise at high ISO with the SL3 than with the 24Mp sensors in the S1, S5 etc. That sensor really is quite amazing. I find these days that my go-to camera is the S1 rather than the S1R. 24Mp really is enough for most things and the ability to abuse the image in PP, even above base ISO, is a step up on what the 47Mp sensor in the S1R can do. I still think the S1R delivers slightly more colour depth and at base ISO there's still a benefit there, but I find the S1R to degrade quite quickly once past about ISO 1600.
