BTC is secure, FAST and more reliable.
Paypal has high fees and chargebacks.
To be honest, I'd rather say Paypal is faster than the Bitcoin. Because sometimes you will had to wait more than a few hours for your transactions to be confirmed by the network.
But I still prefer Bitcoin over Paypal because of certain features that Bitcoin has.
Bitcoins cannot be sent to the bank unless we trade with online users which is too risky while PayPal has this feature which is safe. Except that the difference between the two is that bitcoins are crypto currency and PayPal deals with fiat. PayPal is more secure than Bitcoin in terms of the Government policies.
