Teeth whiteners are all basically the same materials. They are either hydrogen peroxide or carbamide peroxide. Over the counter products are just lower in percentage than products from a dental office. If you want to experiment with a lower cost OTC product, don't be surprised if you don't get a great result because it often is a slower and more gradual process. If you want more immediate gratification and don't mind the additional cost, then do in-office whitening and follow it up with take home whitening in a custom tray.
