What is the best Agile project management certification?

When asking 'what is the best Agile project management certification?' people will often mistakenly say Scrum Master certification. That would be wrong because Scrum is not a project management method, and a Scrum Master is not a project manager. In fact there are really only two main Agile project management certifications - AgilePM, and PRINCE2 Agile. Determining the best Agile project management certification depends on your previous experience. If you have a knowledge of PRINCE2, then take the PRINCE2 Agile certification. Without a knowledge of PRINCE2, take the AgilePM certification.
