The fundamental difference
Uses satellites to calculate its position and the mobile network (SIM) to send it to your phone. Works anywhere with coverage. Updates every few seconds. Requires monthly subscription.
Uses Bluetooth to communicate with nearby iPhones on Apple's "Find My" network. Those iPhones anonymously send the AirTag's position to Apple, who forwards it to you. Without iPhones nearby, the position doesn't update.
