Was Palpatine stronger in dark empire or the rise of skywalker?

So in both legends and canon, Palpatine has 2 different peaks of power. His power during the dark empire comics, and his power during the rise of skywalker movie. We don’t have a ton to go off of for him in canon, but from what we can see, is Palpatine more powerful in Dark empire, or the rise of skywalker?

Bonus question: how do these versions compare to Palpatine in revenge of the sith or return of the Jedi?
