The most powerful Semblance can mean anything. A Semblance that grants you absolute immortality can be the most powerful. A Semblance that can give Death to anything can also be the most powerful. Classic story of the 'best' spear versus the 'best' shield, like Avalon vs MEDP. I'm just assuming that someone's Semblance can take on the form of something similar (or identical, because why not).
