Apparently people actually putting more than surface level thought into GT is enough to "trigger" you, it seems.
BoG SSG Goku is at best Multi-Galaxy level from the statement by Toriyama suggesting Beerus could destroy the Kaioshinkai. As far as comparing it to GT characters, similar levels of Multi-Galaxy feats are reached with S17 Arc Base Goku charging his Ki against Freeza and Cell shaking both Hell and Other World.
Super Manga SSG Goku is also Multi-Galaxy level from his universe shaking, with it not being Universe level like its anime self due to there being no solid timeframe given on how long it'd take from their clashes to destroy the universe. It's more impressive than S17 Arc Base Goku's feat, but not on par with SS4 tier feats and scaling, particularly when we're shown later that someone with little experience in healing like Trunks can still fully restore Goku's Ki to the point he can go PSSB, whereas Kibitoshin is stated to not have the ability to heal someone of Initial SS4 Goku's level of Ki.
Super Anime SSG Goku is Universe level. Comparing him to GT, him and Beerus being able to destroy the macrocosm with several punches is still less than half as impressive as Super Yi Xing Long who's minus energy was stated to eventually be capable of destroying all the realms of the DB Universe. I'd plug
this thread for a more detailed explanation on why the GT high and top tiers are Universe level, but the gist of it is that the Minus Power Energy Ball is a condensed version of all of Yi Xing Long's minus energy (of which can destroy all of Universe 7's macrocosm) and Yi himself could survive a Big Bang Kamehameha that ought to be stronger than the kick which neutralised the former attack, with Beyond Limits SS4 Goku and Vegeta being on a similar tier to the extent Goku could somewhat budge Yi enough to be commended by him.
