if you only plan on paying for stuff online, shopping with paypal would be the better option for you. but if you are expecting to receive and send payments then i recommend bitcoin. because paypal just keeps limiting my accounts whenever i receive money. 
Only two of my friends use PayPal for selling staff on ebay and both of their accounts were frozen for about 6 months. Later they have unlocked them, but so much time was wasted and their money was frozen for soo long. It is a disaster.
Hope that more and more stores will accept bitcoin for buying and selling. If bitcoin brings trading freedom, than I am two thumbs up for bitcoin.
