I love Stripe and will use it for any future projects I have, the minor additional fee per transaction is well worth the full set of Stripe Radar fraud detection features, it’s saved me a lot of money and headaches, and the fraud rules are incredibly useful if used well (ex: I block prepaid cards in some circumstances to prevent abuse, require a billing address match for U.S. cards (due to high rate of abuse in the U.S. with prepaid cards and privacy temp cards) or reject them, etc.). Almost everyone has a debit or credit card, even in less developed regions unless they’re younger.
I’ve used PaymentWall for years, and while it is amazing for the consumers giving them the option to pay with local methods and currencies, it’s truly a pain in the ass waiting one month, sometimes two or three months to get a payout. Also there’s no way to track refunds, so you get a customer coming back three weeks after requesting a refund wondering where it is, and you just have to be like “fuck, who knows, not me”.
PayPal… is PayPal. It will always have its place, and has some good features for business clients, but not much to say about the oldie.
