Well, if we have to be painfully accurate, .PRO was out much before .PW was even a good idea in someone's mind
And they do carry out their fair share of diversities. .PRO is still a generic TLD, while .PW is a ccTLD (country specific for Palau). And while .PRO has been carried around with the clear idea of Professional in mind, .PW has a more shady background, being one of the choices for easy regs to send spam messages. That is why in initial months after release .PW had suspiciously high number of registrations (don't quote me on recent stats tho, never really followed how its development was going).
