Paypal is hassle to others because of security measures it's giving to their users and its just fine.
Bitcoin is easy to use because no security measures are given here.
Therefore, both are useful depends on the person's need.
Like here in my location, withdrawing cash is easy with bitcoin here so I will choose bitcoin. I don't have bank account that's why I can't use Paypal for withdrawing cash.
I dont think you can choose between these two and that is only because both can be used for other things off course can you also pay things with paypal or bitcoins but in my opinion bitcoins are just for investing and not secured to pay with you know. There is paypal the secured way to pay something online!
There are many sites which only accepts paypal and not bitcoins. So we cant boycott Paypal even it has high fees. Where there is an option of bitcoin and Paypal, i will defiantly recommend to use Bitcoins over Paypal.
In short PayPal may be present but future is only of bitcoins.
