if you are asking for this bitcointalk.org Community than I can say with no doubt the most using payment processors of the community is 99% bitcoin. I saw people asking to pay them in paypal and willing to pay via paypal also.. but Paypal is not preferred because of their money reversible policy. I saw above posts I think if you are just want to sell something individually than you better go with bitcoin.
Most of the time for the purpose of buying or international shopping I prefer PayPal for its return back policy. As quoted for individual needs or exchanging goods within two persons can choose bitcoin. But with bitcoin both needs to have trust over each other or need to use an escrow. Finding a new person with trust through forum is hard.
