Yes, I am reaching that point of Fallen London.
I have been unable to find any recent information on POSI usage… so here you go.
Extraordinary Mind makes SotC 21 a lot easier but isn’t strictly necessary by now, if you’re willing to put in a lot of work and some Fate to get the best gear. Legendary Charisma unlocks a couple unique options but there aren’t many high-level Persuasive challenges out there. Invisible Eminence and Shattering Force likewise don’t have many high-level challenges and don’t have any special options. Each one is also helpful for gaining specific Renown types.
There’s really not much difference right now and there’s currently no way to change. Unless there’s something specific you want to do with the overstatting, there’s no reason to choose right now.

Ah, so nothing has really changed since 1 or 2 years ago. Thanks for the info!
