I think people are underestimating it.

We don't know how much aether the eyes still possessed. At multiple times throughout the story it's been implied that the eyes are effectively limitless in their power. Ilberd is also the first summoner we've seen to perform a self-sacrifice as part of the ritual. The original extreme primals highlighted that sacrifice directly increases the strength of the summoned creature so there's no telling how much more powerful a deiform summoned by self-sacrifice would be. Ilberd seemed convinced that it would be more powerful than even Bahamut though, and the Dreadwyrm was so powerful that we couldn't face him head on as it was.
