Title says it all:  pound for pound, which type of bioroid was superior overall:  Zor’s red command bioroid, or an Invid Fighter bioroid?

The Invid Fighter was more advanced, and the triumvirate pilots fought as a unit. But Zor Prime was more experienced.

So it goes more to the pilots then the design.

However, all bioroids shared the same basic flaw. A head shot would kill, or incapacitate the pilot.
