Frankly, everyone I know who is a PM simply wouldn't be asking these questions. PM's are in charge of making fast decisions on the basis of imperfect information. This 'should I pursue a CFA or an ACA or an MBA or an M.Sc. or...' is silly. A PM needs talent and aptitude more than any particular letters after their name. All of these certifications are fine. Just pick the one that looks like the most appealing to you, start doing it, and see where it leads you. It probably won't be to a PM position, but it probably will be to someplace where you will be happier.
