Voigtl nder nokton classic 35mm f 1 4 vs voigtl nder nokton vintage line 35mm f 1 5 aspherical?
The Nokton Classic 35mm f/1.4 is the one I'd pick for most people. It's faster, at f/1.4 against f/1.5, and it's a soft, classic-looking lens wide open. It also mounts on Sony E, Nikon Z, Canon RF and Leica M, so it works across more bodies. On Sony or Nikon APS-C it frames like about 52mm, which makes it a nice portrait-ish option there.
The Voigtländer Nokton Vintage Line 35mm f/1.5 Aspherical is a Leica M lens only. If you already shoot an M body, it's a fine companion. If you don't, there's no reason to choose it.
Both are manual focus, neither is stabilised, and both are full-frame 35mm lenses. A 35mm is the classic street focal length, so either will suit street work well.
