Paypal is more secure if you are buying goods, if you are buying with bitcoins use a trusted escrow.
Choosing the escrow is also another important task.
If you are selling goods then go for bitcoins
Yeah that's correct, I was a active user of paypal before the existence of bitcoins, but with the existence of bitcoins I don't think that there can be any better services then bitcoins, so for me paypal has become a history now, I mostly prefer bitcoins to do the transactions online with less time and with less transaction fees.
The transaction fee is much less than the paypal. If you are a online seller, you have to pay a lot of transaction fees.
