Do you know I have heard similar things (Paypal is not as good as you think) from friends based in US. I might have affinity for them, perhaps yes, most probably because I am far from their reach but I bet them, if they continue this way, the nearest future might not have anything for them because payment processors are becoming very competitive and customer friendly and I'm afraid, they might be left out of that customer satisfaction.You will hate PP once you have a problem with it! PP is not that good as you think!
If you are buying physical stuff online then PP is a good choice because you get covered in case you get scammed but did you know that, PP will not protect you in case the things you buy is a service?
Even if you have proofs that the service has not yet delivered, PP don't case about it! You can only protect yourself.
