In my eyes they are both good and there is no one that is better, they both have their up and down sides if you ask me.
I love them both and I'm also using them both these days.
I think they have their strength and flaws. But if you compare the two people who own PayPal will use PayPal while those who owned bitcoin will use bitcoin. The deciding factor would be the site where they are going to use their credit. If the site doesn't accept bitcoin, even with you having million of bitcoin in the stash, you will be a force to use PayPal and vice versa. The good thing with PayPal is that it is recognised by more stores than bitcoin.
