Who is the least powerful Arc Moro character to surpass Gogeta PSSJB?

[Goku9001]

But Broly only transformed once, and in Super Hero still can’t use his power. LSSJ Broly is merely an hypothetical.

Isn't that the case with Kid Gohan? Gohan couldn't even use that power voluntarily and only used it once against Cell, and yet it serves as a point of comparison for Goku and Vegeta in the Buu Saga.

When Goku compared Broly to Beerus, he absolutely was taking into account FPSSJ Broly's power. Toriyama even claims that "not even Broly would beat 'Controlled Cell Max'" and that definitely wasn't referring to just Ikari Broly.
