Depends what else you want it to do. Super Cubs are very very good STOL aircraft, very cheap light and simple. But if you need more range or payload or passengers then the answer changes. If you need to operate in IFR the answer changes. If you need to operate in harsh climates then turbines are better, but they cost more to operate. So, dropping one man on a sand bar in a river - super cub, dropping a climbing team on a remote glacier - Pilatus PC6. The Fiesler Storch could fly virtually standing still, but they haven't been made since 1945 and they never could carry much or were particularly reliable, running one now would be like running a pre-war Mercedes as a daily driver, just not practical.
