Which is better, a level 1 airbag or a level 2 airbag?

Airbags are classified into two levels: Level 1 and Level 2. Level 1 airbags explode in a single burst, while Level 2 airbags have two igniters that ignite at different times. Their prices also differ. Generally speaking, Level 2 airbags are better than Level 1 airbags because they can control and adjust the airbag deployment speed and inflation time based on the collision time, collision speed, and collision force, resulting in less harm to the human body.
