> I never got support via the old PayPal donation button like I have via Patreon

Sounds like Patreon helped you after all.

I'm not saying that they promote or market you, but having the name (much like Apple) seems enough to encourage people to pay you.

OTOH, I certainty don't think that their cut sounds like a good deal; rather, it sounds more like your options are a bad deal or no deal at all.
