No matter how you look at it MiH showed up it's limits (now that I think even Bohemian Rhapsody did so to some degree, since it also set the whole world into chaos)

From what we can see of it though, GER does seem to be invincible at least, as well as extremely powerful against other Stands, even other combat-oriented Stands like King Crimson. It's just that Giorno only has limited access to it.

We don't know how limited that access is. We don't know what the limits of GER's ability are. We can't even definitely say we know its range. There's so little information regarding GER since we only see it in one fight, and briefly at that.

We do know that it can defy time and even fate. We know that Giorno has some degree of manual control over it,  and that it activates automatically to protect Giorno. We know that it can directly overpower a Stand as strong as King Crimson, one of the top-tier close range types. And we know that it allows Giorno to fly, something no other Stand in the series can do (except kind of Made in Heaven? There are moments when Pucci's definitely flying with it but later he gets stuck in the ocean so it's limited to some degree)

While GER has very intense limitations on the act of summoning it (reminds me of Tusk ACT 4, actually)  the actual Stand itself, independent of its summoning method, overpowers just about every other Stand in the series based on what we know.

We can speculate the exact limitations of GER till the cows come home, but unless new information gets revealed, we can't treat any of it as accurate or reliable.

That said, I've got a post on here somewhere about why, at least thematically, GER deserves to be and should be the most powerful Stand.
