The 'God of Guardians' mentioned that if Baam learns the 'Black Hole Technique' he would have an "understanding of shinsoo different from any other regular".

Like you said though, everything is conditional. Him having a different understanding of shinsoo doesn't exactly mean he's stronger.

(Edit), the 'God of Guardians' exact words were, "So if you end up being able to use this skill, you will have mastered a control skill on a whole other level from those other regulars."

He says "control skill" which leads me to believe he is referencing the skill itself and not Baam's actual control of shinsoo.
