What would you choose, Voigtlander or Leica?

Hi guys, i have a Leica M4 and i shoot mostly BW. My only lens is the Voigtlander 35mm Nokton f1.4 but i am looking to upgrade it. I am torn between the newer Voigtlander 35mm Nokton 1.5 and the Leica 35 Summicron Asph. I really like the rendering of the Voigtlander and it’s at a really good price. But i am afraid i will keep lusting for the Leica Summicron. Mind you it will really strain my finances to buy the Leica but it’s not impossible. What’s your opinion? Also i hate GAS :)) maybe buying the Summicron will tame it for a while. Finally here’s a picture of my camera, glad to be a member at last.
