There are really no bad choices in 50mm class M mount lenses, they are all good, although some really are spectacular. As a rule you can never go wrong with Zeiss or Leica (in my opinion at least). If you need to save money all the Voigtlander choices are fine as are the Konica M's. Leica set the bar pretty high in M mount lens field, and the few companies that have ventured into that market must (of necessity) have a good product.
