No, it's not. He's powerful, but in terms of versatility and feats, the heralds are way over him.
Now, that may change. He prove to actually be in their league. At the moment, it's a wait and see thing.
The day Extremis can take control of Thanos's tech, or Celestial tech like Prosh (Poccy's ship in the old days), etc, is the day I burn a few issues of IM. 😒 Let's be real, Earth tech is great for where it is, nobody denies that. General level is quite below most alien tech. Couple of people like Doom, Reed, etc, are over most alien civilizations, but that's not a general view.
But as good as it is, there are some kinds of technology that just dwarf it. And IM's tech isn't the best on earth by a good stretch. Doom's is better, Reed's is better, most of what Forge can do is better (not sure if that counts), Poccy's is better, Ultron's is possibly better (debatable, but the tech is at least comparable), and a few others.
