They are both good, but I think we cannot compare them because they are both very different.
The bitcoin wants to be a real currency, Paypal just wants to be a pay method and is not a currency at all right ?
Overall I do like the bitcoin more because its faster and also more secure and cannot get limited.
Finally a guy that is exactly saying what I would say, I'm also thinking the same thing, you cannot compare this too.
The bitcoin is something to pay with and is something that wants to be a currency.
With paypal this not the case because its just a system that accepts money and convert them to other currency's.
I think overall there is no chance we can compare them because they are both doing different kind of stuff.
