Re: M-mount lenses: Which ones perform well on Leica and Sony?

My Leica set is basically all Voigtlander since most of them perform similarly on both Sony and Leica. The only lens showing issues on the Sony sensor stack is the CV 28/2 Ultron but it's a very good performer on the Leica. (without breaking the bank)
My set is: CV 12/5.6 III, CV 21/3.5, CV 28/2, CV 35/1.2 III, CV 50/3.5, ZM 50/1.5C, CV 75/1.5 and Leica 135/4 TE.
I love the CV 21/1.4 Nokton on the Leica but knowing myself, I would not use it much as I prefer small/light lenses for the Leica camera. I am thinking of adding the E-mount version to go with the CV 50/2 APO for the Sony.
That's a pretty comprehensive collection!
I have the old 12/5.6 LTM, which I kept for it's tiny size. It shows some color shift along the edges on the M240, but not as bad as on the M9. I also have the CV15/4.5 III. I haven't used either that much lately.
The main kit is 21 SEM, 28 Lux, CV35/1.7M, 50 Lux ASPH, 90/4 Macro. I'll swap out the Macro with the 90AA sometimes if I need the speed or background separation.
I've been tempted by the CV50/1.2 but like the smaller size of the Lux ASPH, despite the ninja-star aperture shape between f/2.5-5.6 and the mid zone dip that becomes most apparent between f/2.8-4. Perhaps because of this, I find I use this lens mostly between f/1.4-2 and around f/8.
If Cosina releases the 50/2 APO in M mount, I would definitely get it as my 50mm all-rounder.
I'm curious your thoughts about the 50/3.5 on the M10... I think I've read that the ergonomics are somewhat annoying. Given that the block diagrams for all 4 versions, as published by Cosina, seem to be the same, I wonder if finding one of the collapsible versions would be worth it?
