SEPA Direct Debit has pretty good UX, I find. Just enter the bank account number, accept terms, done. In theory it's a bit more complicated as for B2C you're supposed to collect a real signature (which no one does) and for B2B there are additional rules (which most merchants also ignore), but in practice it works reasonably well. B2B SEPA direct debit is also much better for the merchant as money that has been successfully transferred cannot be refunded, unlike credit card payments where you can get chargebacks for 120 days...
