Would Hector make changes to his scheme and come up with a different gameplan to defeat Achilles the next time they met? Or would he say, "I don't need to change anything, my sword just needs to execute better"?
But to answer your question, I would rather win the right way. I would rather win a couple championship and having them mean something, than winning multiple championships and getting some (or all) of them vacated (or even just the knowledge of shady things that happened during that time).
