Use Prolific when
You're running a study: several questions, randomisation, experiments, detailed screening or an ethics process.
Use 50heads when
You need a quick, trustworthy read on one thing (which name, which image, which line) and you want it now, at a price that lets you ask again tomorrow.
Many teams use both: Prolific for the study, 50heads for the dozens of small decisions around it.
