you mean methods where there is no Chargeback ? you can't chargeback Paypal (sent as gift) , Paysafecard , Wester Union , CashU , UKash , MasterCard ....
BULLSHITPayPal even as a gift, MasterCard and all other credit cards, bank transfers and almost all other forms of fiat can all be reversed.
I only sell for cold hard cash. It is the only form of fiat that is certain to not get reversed.
localbitcoins.com doing an in person cash for BTC deal with a highly reputable dealer is the only way to be certain.
Never heard that Paypal sent as gift can be chargebacked .
still you have UKash , CashU , Paysafecard , safe 100% .
