HYS also casually negated YG's palm power. Neither was really going all out so we pretty much only have HYS's judgement. If I wanted to be callous I could even say that it's rather sad that a mighty blow from YG's Sad Palms could be completely dissipated by a flick of HYS' finger
Nonetheless, power delivered isn't really the important part since any solid blow from a Great to another Great is a trump. A direct clash always ends up an internal energy struggle and we simply have no data on what was up with GJ at this point (beside conjectures based on 9 Yin).
