New Gods are a lot beefier post-Flashpoint. Darkseid has one shot Superman, and Orion laughed off Supes literally speed blitzing him into the ground. Orion also had a dust up that destroyed the solar system he was in. Even random mook New Gods were strong enough for Sinestro to bust out Parallax to take down.
Current Darkseid is the new one that killed the Quintessence and hasn't done anything else yet. I'd imagine that even thousands of planet busting attacks would be insignificant to someone who ganks the Spectre and friends, but we don't actually have durability feats for him yet.
