i think g may have one-upped odin at one point, but odin seemed more frustrated. it was odd though--he stopped, called him a bastard and seemed to call on his forces, all the while maintaining tp contact and battle?
we also saw that galan (in g's mind) seemed to be confused and very concerned about the plight of his universe and galan didn't seem to realize that he was being assaulted via tp the second time around. not sure what odin's end goal would have been or if it would have been successful. it was also impressive that even after thor's blow, odin seemed locked in the tp world that g created for him.
as far as it went, i'd give a slight edge to g in that battle in terms of who was more impressive, but it was entirely indecisive as it was not yet ended.
