I'm not talking about metal angle or strap bracing. I'm talking about steel.

Is this stronger than ply bracing?

No It's not.
Was the power truss system noted on your plans?
Ply bracing is 6.0kn/m.
If they did change the system to ply they would have put more in. I can't see the benefit of using solely the power truss system on a house. Short panels and difficult sections to brace yes, but not for general bracing.
