From what I heard, depth armors are a tiny bit better against regular monsters too, but not by a significant amount.
The "nebula is old meta"-argument does kinda fall flat for me because there are good chances they'll be best-in-slot again with later updates (see enchants here).
I'm not super against having hammers here, since it helps not getting screwed over by RNG (which is generally a positive thing), but then we'd have the same suggestion for the next piece of gear that doesn't have it.
