The error message states that you have put wrong address for shipping during checkout.
Paypal accepts correct address everytime you place an order. If the address you are using for shipping is not valid then paypal rejects it with the error message you are getting.
For other payment gateways its fine. There are some payment gateway who validates your city, postcode, state and country. If these details are not correct then they will reject the payment and give you error message.
So better to test paypal you need to fill up valid shipping address during checkout.
