This is the exact problem people have in the OPM community. It sounds absurd, but all evidence suggests it to be true. God is vastly inferior to CF Garou in every way. Garou only received a fraction of the small power that God offered, it's easy to deduce that they are incomparable, in two different leagues. CF Garou matched full power Saitama, but Saitama grew strong enough to stomp him fairly quickly. It doesn't change that CF Garou was temporarily equal to Saitama's full power. That, in addition to who knows what kind of hax God will have, is pretty suggestive evidence to me that God is stronger than this current Saitama, not that he would definitely beat him or will beat him, but at the current moment, I highly doubt Saitama is on God's level.
