Why would someone use AirDrop?

Why would someone choose to use AirDrop? It seems like a relatively unknown or overlooked feature on Apple devices. Is it really worth utilizing? What are the main benefits that AirDrop offers compared to other file-sharing methods? Is it secure enough to send sensitive files? How does it work exactly, and is it user-friendly? I'm curious to understand the practical applications of this feature and whether it's suitable for both personal and professional use. Could you elaborate on the scenarios where AirDrop would be particularly useful?
