does this answer you question? from death battle and the man you supertards love so much

'lol the what is canon debate is fun for a joke but so lame when people take it seriously"

he know the stats for superman was from comics and non canon

"no matter what super-saiyan god is it will not changer the death batte unless it compleletely destroys the main purpose of goku character"

so it was not powers but character

"and even if it does its still veny unlikely it'd change things even slightly as expressed in the most important part of our recap (after the arbitrary yet expected measurements)"

ar·bi·trar·yˈärbiˌtrerē/adjective

1. based on random choice or personal whim, rather than any reason or system."his measurements were entirely arbitrary"

   synonyms:

   capricious, whimsical, random, chance, unpredictable; More

   • (of power or a ruling body) unrestrained and autocratic in the use of authority."arbitrary rule by King and bishops has been made impossible"

     synonyms:

     autocratic, dictatorial, autarchic, undemocratic, despotic, tyrannical,authoritarian, high-handed; More

   • MATHEMATICS(of a constant or other quantity) of unspecified value.

so it did not matter what death battle said it is all arbtrary god mode would not change anything becouse thay control who wins god mode would not beat superman only if it changed who goku chraracter is and thus is bull shit
