Well, Freeza's true form is definitely below MUI Goku (ToP arc) as that was the last power of Goku's that he witnessed, and he went Black to combat all three of his enemies on the planet Cereal. I can't say for certain what his Golden form multiplier would be now as we haven't seen him use it, but I'd put his Golden Form at best around Jiren (ToP), maybe above Angel Moro if you were to suppose Freeza simply wanted to show off his Black form and didn't necessarily need it to reach UI tier levels.@Papasmurf
I just love the idea that the UI form Goku can use his emotions and become Goku's strongest form again.
As for Frieza, what multiplier do you give the Golden form over the True Form? What multiplier do you give to the Black Form over the Golden Form?
