that difference in power is more of the person who they turned into though... That he could turn into Kenpachi just means Kenpachi needed to beat himself (which seems to be something every manga/anime seems to NEED to go through at least once...), whereas Yhwach's copy was able to copy his memories... Which basically include having access to a huge set of experiences.
