That's where we get into the dilemma of feats vs. accolades.
Besides her whole 'sploding an entire city of Sith thing, Abeloth is not necessarily the character with the best feats. We have confirmed planet-busters like Palpatine, Nihilus, ritual!Vitiate, etc.
But the Anchorites of Mortis are excellent examples of this. According to narration and supplementary texts, they are powerful on a level beyond Jedi and Sith. Yet in terms of highly destructive feats, they don't actually demonstrate anything as remotely impressive as Palpatine's Force storm or whatever.
But they are clearly intended to be divine beings while he, at best, is an eldritch aberration. And Abeloth, if you believe the legends, cowed the Son and the Daughter together.
I think it's best to have a compromise, look at feats but also how they fit into the greater context and their accolades.
