Genis Vell he can shunt off all the energy Blue Supes could ever hope to use against him......................universal telepath allows him to know his moves, then keeps sending him to the microverse.
Blue Supes once wrestled and practically stalemated an angel if I can remember. Too bad it didnt mean much as inconsistant as Energy Supes was at times.
They both seem identical. Maybe 5/10 both. Blue Superman can turn intangible, create force fields, create dimensional rifts, control all forms of energies, and his other abilities have been enhanced.
Genis survived the big bang and had a key role in the death of Eternity. Plus he too can control all energy, without the disadvantage of being made out of said controllable energy.
Superman should have stayed in this form in my opinon, he seemed so much cooler than his regular old self... I kinda think the fight could go either way Vell is pretty tough.
