Agreed! Using Safety Seal brand installation tools and plugs, I repaired countless dozens of tires all thru the 70's and early 80's. Never had a single repair go bad. Safety Seal brand plugs are indeed superior to the knock offs. As long as the puncture is on the flat contact patch part of the tire, it will work fine. There are cases when the puncture hits a steel cord. If the cord is badly damaged and you can see the broken wires or, the hole cannot be reamed without causing damage to the cord, then the tire is shot. That's fairly uncommon.
Caveats... I don't know if plugs can be used with run-flat tires. They can be used on tires that have the internal sound deadening blanket but your supposed to break the tire down and verify the padding material does not get pushed away.

OTOH The mushroom patch and its 17-step installation process is an engineering marvel. You've got to clean the inside of the tire so the new one will stick, then vulcanize it together somehow, push it in with a "cowboy spur", paint it with bead sealer, etc.
You forgot the more crucial steps: Hold your left foot up while touching the top of your boot with your right hand followed by hopping on your right leg. With your left arm, pat the top of your head. This invokes the gods that makes rubber glue stick when Venus, Mars and Jupiter are in retrograde with the accretion disk of Saggitarious A's black hole. Do NOT forget this important step or the hour you spent scraping rubber, waiting for the solvent to dry then waiting for sealant to setup then waiting for the final layer of sealant to dry is all for naught.
