Only Stands that could match the power of Gold Experience Requiem are Over Heaven Stands. However, they are not canon, so I shall not include them here. And even they could still be defeated if Giorno got the first punch.

As for Made in Heaven, it has a weakness that Gold Experience Requiem can explot, and that is that it has both cause and effect, both of which can be nullified by Gold Experience Requiem.

While Gold Experience Requiem certainly isn't omnipotent, it is without doubt the most powerful Stand in canon universe.

Oh and, a theory: the Requiem Stands are named like that because a requiem is the last thing you "hear" before you are buried, signifying that it is impossible to survive an encounter with Requiem Stand.
