I understand that somewhere paypal to fail, but I think they're working on to cover all parts of the world, I am happy with paypal, in my case I think it's one of the best payment processors we can find on the internet , has many options that we can use as consumers, for example we can return our money if a purchase we did not like, or if we do not have the service that we bought, I think few payment processors do this.
for that and for the services offered to me I prefer paypal. after the next processor I like is payza
