Certs differences , which one to choose?

I was wondering if I go through the PMP, Prince2, or Scrum cert, in fact we have planned in our enterprise to visit a formal course for the Scrum Master Certification.

But what's Scrum? it 's an iterative and incremental agile software development framework for managing product development. It defines "a flexible, product development strategy where a development team works as a unit to reach a common goal", challenges assumptions of the "traditional, sequential approach" to product development, and enables teams to self-organize by encouraging physical co-location or close online collaboration of all team members, as well as daily face-to-face communication among all team members and disciplines in the project.
