Which is the greatest technique in Tae Kwon Do?

Answer 1

The greatest and most widely used technique used in Tae Kwon Do is the roundhouse kick (otherwise known as the "round kick"). Its advantage lies in its simplicity: it is easy and quick to execute and is the fastest way of scoring a point.

However, the kick that is usually considered the "greatest" as far as complexity is the 540 kick (commonly known as the "tornado kick"). This is elaborate and difficult to execute.
