Most people who shoot rangefinders eventually gravitate to the 35mm focal length. I believe, the benefit of a rangefinder is greatest at that spot (35mm). I've been shooting the 1.4 Nokton II for the last year, and it's a very good lens w/ a lot of character with a relatively small price. Very practical too, given size and weight considerations and its' 0.7m MFD with a "normal" 43mm filter thread. Much better option in my mind then the pre-asph Summilux. True, wide open it is a bit soft, with crazy bokeh (which I like), but stopped down it's crisper, and that gives a whole bunch of variety in one lens. I shoot B&W film; I don't know anything about its' digital performance.
