MSI IPS vs Rapid IPS Panel

MSI claims "Rapid IPS is the latest technology that delivers 4x faster response time than a normal IPS panel." How does it stack up against a traditional IPS panel? In this video I compare the response times between the MSI Optix MAG274QRF (rapid IPS) and the MSI Optix MAG321QR (normal IPS). Very clear different in UFO test but in real world scenario not that big of a difference unless big into e sports titles and want the best. Rapid IPS is the clear winner but you have to decide if the extra $ is worth it. Which would you pick?
