Is PRINCE2 or AgilePM better?

Whether PRINCE2 or AgilePM is better depends on your organisation's current situation and goals. It is not straightforward to say one is superior to the other. Consider where your organisation stands and what you hope to achieve when making this choice.

If your organisation already uses PRINCE2 and wants to start managing projects in a more Agile way, the best step would be to investigate and adopt PRINCE2 Agile. If your organisation has not adopted PRINCE2 but wants to achieve the benefits of Agile project management, then adopting AgilePM makes more sense.
