In general, when reality-warpers fight against other reality-warpers, rules of abilities get thrown out the window and it purely becomes a battle of who's strongest, aka who has the best feats. Because warping reality causes all the rules to change anyway.

This is why GER is a problem child for versus fights. We only ever see it used like twice, and it's left deliberately ambiguous what its limits are.
