OnlyFakes had a problem with Patreon and changed to ccBill.
But it’s difficult to make a comparison, because onlyfakes is mostly used to generating actual porn rather than just nonsexual nudity, so the two are very different.
I’ve never heard of any site using ccBill before (and OnlyFakes is based in Finland, so it might not be available here) but there’s a review at https://www.merchantmaverick.com/reviews/ccbill-review/
