I have found, as mentioned, that I like good sharpness but with moderate contrast. The SC version I had seemed ok but in viewing my images from it over more than a dozen rolls and in differing subject matters and lighting I was rarely wowed by it. Again a matter of personal choice but the OP asked for opinions on this set up and I had it.
Leica brag? Why would I brag about a beat-up ugly user M3 body and an ugly Summicron? Again just sharing experience and opinion. I like a few VC lenses, got the 15mm and the 75mm and like them tons (had the 35/1.2 and sold that off too). But when it came to the reason for a stealth quiet RF to counter my Nikon SLRs and decidedly not quiet Contax G2 the VC bodies to me did not give me what I wanted vs very reasonably priced and classic Leica bodies that have well-deserved reputations.
