both things can used also for more things but what i recommend you is that you need to use the paypal method as a online paying method and when you use bitcoins make sure you make money with it dont spent it on bullshit,.
to me as i have never use paypal therefore i have no clear idea about this, i am only using bitcoin and not anything else. to me bitcoin is the best of all transaction more reliable trusted and profitable than anything else.
i agree with you i also have never use Paypal , but i think bitcoin is much more better than paypal or other and you are right that the bitcoin transaction is very easy and faster and there is no transaction fees of bitcoin if you using for shopping .
