If you’ve started working, you might want to take a paper that is more closely related to your role at work. If your role has to do with management, P5 is the logical paper to take and vice versa.
If you’re not working yet, take a paper based on which paper you enjoyed and understood more at the fundamental level. If you enjoyed and understood F9 more, then take P4 and vice versa.
Whatever paper you decide to take, think properly before taking a decision.
