A bacon strip is doubled over on itself when it goes in the tire, and hence fills a larger gap; with Dynaplugs, I more often have to shove in two of them in order to stop a leak.

No method is perfect: once, in a hurry, I jammed the Dynaplug into a tire and yanked (hard!) the tool back out of the tire...And the plug tore away from the brass piece and came out of the tire.
