Thanks for that very concise and factual explanation of CMP.
As to the original question, as with any gun, the buyer should ask themselves certain questions, 'what is the gun for?'. Are you looking for a historical piece, for use at competitions, as a fun shooter, are you concerned about maintenance requirements, costs of ammo, what is the availability of each weapon now and into the near future, etc.
Answer those questions and you'll come to your own conclusions.
