I think PayPal is better. Payoneer is good though not to totally discredit it. It has been around for a while now. The thing is that for online payment, PayPal is the best processor so far obviously. It may not just be because it is secure, other processors are just as secure with fair charges too. It is the most widely accepted.
One of the challenges I find with payoneer is the high minimum for withdrawing to your local bank account Other than that, it is also good and the fees are fair enough. Plus, you get to request for a payoneer Mastercard which you can use at any atm and withdraw with your local currency. I think if more sites and people include payoneer as a means of payment. It would function just as good as paypal does.
