It's hard to compare these two as each of them have they're own good and bad parts.
Paypal tends to be more secure within terms of account creation, that you have to verify that you are real
that you have a bank card a home address and so on, and there is a possibility for a refund in the worst case.
On the other hand Bitcoin wallet is for anyone, even a dog could open one and transfer funds to his beloved cat friend.
So basically both are great payment options and if you don't have anything to hide you can sure use both of them.
All tho paypal has many more restrictions and fees than bitcoin, it's just well more known and accepted more around the world,
than bitcoin is currently. But that is changing rapidly , so whatever works best for you.
