Just read what he writes about Voigtländer 35mm f/1.4 NOKTON Classic - "This Voigtländer lens is significantly softer at large apertures than LEICA's first SUMMILUX 35mm f/1.4 (1960-1995), which is LEICA's softest modern 35mm lens".
I had both lenses and wide open Lux was much softer. And all tests and reviews I have read also confirms this (and KR just states the opposite to the obvious).
Just one example:
In fact, I traded my old Summilux for some other gear and kept the Nokton.
