100% bitcoin is much better than paypal,
In paypal you have to disclose all you identitys and you have to give your identity proofs , in paypal transaction reverse is very famous to scam. and i personally saw paypal and the procedure of it is very bad. and their charges also heavy.
In bitcoin you dont have to disclose your identitys , you can just create a hardware or online web wallet and give your wallet address where ever you want to receive or pay the bitcoins. the transaction charges are also less. and more it is irreversible, and about converting to fiat currency their are so many exchanges where you can convert it one is like localbitcoins.com which is having so many user who are ready to buy or sell and do transaction through bank transfer.
But you have more protection using Paypal. You can reverse a payment if you are scammed by somebody else.
There are alot of difference between these two because i like to pay some things that i bought online with paypal and i like to pay other things with bitcoin most of the time using bitcoins only for investments and not for payments.
