The offers from the offerwalls are generally called offers. The offers like Android, iPhone, Register, video - these offer don't require your profile survey, but depend upon the country. And the surveys through the offerwalls, like OpinionSurveys through the offerwall OfferToro - it depends upon your profile survey. And any kind of survey, except the offers like I said above, requires profile survey.
Now coming to a good offerwall, to me its Persona.ly , TrialPay, OfferToro. They will credit you. And if you have any dispute, their representative will response you at least.
