Battle will be diff to them 2 but these 2 are strongest omnipotent god in anime but in comparison zeno want to erase simbai before he attacks .if simbai otutsuki want to win he must want to put zeno in infinite chakra loop so zeno got manipulation by simbai zeno can't do anything can't even erase or save from there but note these 2 are strongest omnipotent god of i had pick winner lord simbai otutsuki win with high diff
