Their descriptions don't show stats in terms of improvement, so I have no way to compare them with vanilla prosthetic organs and limbs.
Also tier 2 and 3 augments use the same slots (some at least, didn't check them all).

I am wondering how a pawn with full T3 augments + astarte gear compares to

- vanilla (hyperweave+ cataphract)
- Adeptus Mechanicus: Armoury (hyperweave+ tempest scion+adamantine flak helmet)

Astarte seems under powered for the amount of materials, research and crafting needed. Tbh I only had pawns with black carapace+blood angel armour so far. But compared to adamantium flak helmet, tempest scion armour and hyperweave (pants, shirt, cloak, duster) it was not great.
