I can only speak for the ones I have used:
35/2.5 Color Skopar
Mine is the LTM pancake (PI) version. Superb image quality, small, and very short focus throw. It's a great lens for general purpose. Very cheap secondhand. I see absolutely no reason to upgrade to a much more expensive Leica lens.
35/1.2 Nokton (Ver 1)
Fantastic lens. Although it's big/heavy this isn't a lens I would use for general walkabouts so that's not an issue for me. Plus, it's only big/heavy compared to tiny RF lenses - a dSLR user wouldn't even consider this as a big lens.
50/1.5 Nokton (Ver 1)
Mine is the ltm version. Very good quality. I see no reason to seek out a Leica 50 1.4 for marginal improvement at a much greater cost.
21/4 Skopar
Was quite nice on my M8 but I'm a bit unsure how it'll work on my M-E (hasn't arrived yet). I've conflicting reports about this lens on digital M. It's a really nice small lens though and I have no need for faster than f4 at this focal length. I got mine extremely cheap used as it had a small chip in the front element. So performance for cost is high.
