Sama mo na yung debate about using compressed air vs nitrogen.

I'd probably get this much anal about tire plugs if we're talking about space shuttles and airline tires, where each wheel is filled up to hundreds of psi.

For road vehicles, any half-decent plug will work. Just know the limits of the tire...... that means, it's probably a bad idea to track the vehicle or drive it up to its rated speed index after a puncture.
