My hands went faster than my eyes.
There are really a few things to consider. The difference between 1.2 and 1.4 on a 35mm lens in minimal without more background compression that would come from a longer focal length. The colors on the Leica are going to be better hands down. I always felt like voigtlander lenses to be rather flat and less "leica Poppy". I think the voigtlander is a great lens for the money, however the Leica is a step above the rest. Having shot exclusively with this lens over the last 6 months, and having many friends with multiple Leica lenses. I feel confident enough to say that most of the best photos they have taken are with this lens. Color is excellent, Sharpness is great, I would say it is sharper than any other 1.4. The bokeh is different, not are swirly as the voigtlander but pleasing to my eyes. I hope this helps.
