Bitcoin is better but right now PayPal is further because it just gets more accepted all over the world.
They are both good but I think that Bitcoin is already bigger but just not accepted a lot what has to change soon or later.
They are both good, that is right answer, we cant compare bitcoin and paypal. When paypal was invented it draw a big attention, unique service that can make fiat transactions easier. Bitcoin on other side is not a service, bitcoin can be used for much more things.
Paypal will lose its purpose if bitcoin become mainstream. People will not have any benefits from such fiat services.
