Super
The manga lacks its own scaling chain so I'll have to just provide my own ratings.
SSG = 160,000x (Superior to Potara Fusion at that time, beyond Goku's comprehension. So beyond Super Vegito 3.)
SSB = 8,000,000x
BoG God Goku = 1x 2-C
RoF SSB Goku = 50x 2-C
Post-Gravity SS2 Vegeta > SS Black > (50x) > Base Black > FPSS2 Trunks = SS3 Goku > (4x) > SS2 Vegeta meaning Vegeta grew over 200x stronger before fighting Black.
Post-Gravity SSG Vegeta = 200x 2-C
Post-Zenkai SS1 Black > Post-Gravity SSB Vegeta = 10,000x 2-C
SSR Black = Post-Training SSB Goku/Vegeta = 10,000 (SS1) x 160,000 (God) = 1,600,000,000x 2-C
ToP happens. I've got some wanky as hell arguments here but I'll be lax.
SSBE Vegeta > Ultimate Gohan = SS1 Kefla > (50x) > Base Kefla = SS1 Kale ~ SSB Goku ~ Golden Freeza
SSBE Vegeta fights harder than anyone else besides UIS Goku in the ToP according to Jiren. This scales him above Super Saiyan Kefla. Making SSBE and UIS a 50x multipier.
SSBE Vegeta & UIS Goku = 80,000,000,000 times 2-C
Gotta go out of order here to scale UI. In short, during the Moro Saga Piccolo states that Fusion is useless against him due to copying Spirit Fission. Spirit Fission requires tagging and harming the target. Moro easily counters Vegeta's Spirit Fission by just dodging. So that means Piccolo (and Goku who reacts with shock to his statement) believe Moro-73 would be relative enough to tag Blue Fusion. And VSBW accepts Base Fusions as above the strongest forms of the fusees. So lowballing it would be:
SSB Gogeta > (8,000,000x) > Base Gogeta = Goku/Vegeta Blue > (8,000,000x) > Base Goku/Vegeta
Ultra Instinct Goku stomps Moro-73 and then matches UI Moro so the LOWBALL would be...8,000,000 x 8,000,000 or...64 trillion times Base.
80 billion * 64 trillion = 5.12 Septillion times 2-C
Soooooooooo GT Goku would be 326 Quadrillion but ToP UI Goku would be 5.12 Septillion. And this is Granolah Saga Goku.
Okay say I ignore the UI > Blue Fusion multiplier argument. Say we treat UI as 50x Blue, same as UIS. The DBS Broly LN calls the clash between SS1 Broly and SS1 Gogeta 'unprecedented power' scaling them above UI Goku and Jiren. So >80 billion times 2-C. SSB Gogeta and FPSS Broly would be 12.8 Quadrillion times at minimum.
Moro-73 scales relative enough to Gogeta Blue for Spirit Fission to work then gains UI and UI Goku matches that. Post-Moro Saga, Goku and Vegeta aren't aware of anyone on their level scaling SSBE Vegeta above FPSS Broly. And all of that is me ignoring the idea that Piccolo and Goku are factoring in a hypothetical Moro Saga Gogeta Blue. Not Broly Saga.
EDIT: And just remembered. Goku states Moro-73 is the toughest opponent he's had. Scaling him above Broly.
How do I scale UI Moro from base then? Let's just assume it's only 50x (Even though UIS would be 50 x Blue or 400 million times base and UI is superior...) you would get UI Moro at 640 Quadrillion times.
So even if I pretend UI is equal to UIS in power that would still get Moro-73 to 12,8 Quadrillion times. UI Goku stomps him then matches UI Moro who would be at minimum 640 Quadrillion times.
