I prefer PayPal, other than the fact that you can get chargebacked. So BTC is good to defend against that but PayPal is set up better and more convient
It's simple if you're selling something Bitcoin is best cause no chargebacks
if you're buying it's best to use PayPal.
PayPals issue is sometimes it freezes accounts, no anonymity and chargebacks.
Bitcoins issue is it's harder to buy stuff with and it's annoying to convert to actual money or move to a bank account.
