Ok so here is my opinion Gogeta Blue is very hard to power scale because we haven't seen much of him so, we don't know his full power. We know he is stronger than Beerus, and Beerus is Omen level so he is strongest than 1st UI omen but, as the tournament went on Goku got stronger even Jiren said his attacks were stronger than before (Goku was in blue POST 1st UI omen) But I'd still say he is stronger than the omens. MUI is where I think he surpassed Gogeta Blue. MUI is something far stronger then fusion. Also people who think Broly is stronger than Jiren....then hear me out, if Broly FP> Beerus BUT Jiren [BASE FORM] is far stronger than Beerus Brolys wouldn't stand a chance against Jiren when he tried. Ok tell me what you think.
