The Verdict

Prolific and InboxDollars diverge most on hourly rate, and the gap is not small. Prolific leads by roughly 3.0x per hour ($9/hr against $3/hr for InboxDollars). Only InboxDollars supports Checks and Gift Cards; Prolific users don’t have that option. Running both is the practical move: use Prolific and InboxDollars in parallel so one fills in when the other runs low on available surveys.
