Yes Paypal is crappy , Paypal will sooner or later ask you to provide information's to confirm your identity if you receive big amounts of cash or from suspicious accounts , and they can limit your account and you lose your money even if you did nothing .
Bitcoin don't need ID,Passport , don't need a specific age , can't get limited and you can receive how much you want and also you won't get your balance chargebacked by the sender , fees are much lower and much more ... Bottom line ? Bitcoin > Paypal .
Now if you are selling your BTC for Paypal , you may want to be caution because you can get scammed so make sure to trade with someone trusted and note that using a Middleman won't really change anything because the other party can still chargeback so it's not really recommended to accept payments on Paypal .
If you want to be sure that waht you are buying online is going save i would say people for that kind of things you can better use the paypal paying method off course but if you want to do something with bitcoins or invest into something and if it is possible to use the bitcoin use it because that is the best thing to invest!
