Wow, I've heard of moral relativism (the idea that we each have the morals that are true for us, and all of these are equally true), and that's bad enough. But to hear relativism extended to basic facts like efficiency and reality is even more extreme.
So, no, I don't agree with you that efficiency is just a matter of opinion. Efficiency can be calculated, and some designs are objectively more functional than others.
I can see GATW walking up to a Titanic survivor:
"Oh, that design to use carbon steel hulls? That's as good as any other design, it's just your opinion that it's worse, and in my opinion, it's fine."
Or GATW standing over a whale calf who drowned after birth before it could reach the surface to breathe (which happens often):
"Oh, that design to make a fully aquatic, live bearing animal unable to breathe water? That's as good as any other design, it's just your opinion that it's worse, and in my opinion, it's fine. See, in my mind you are still alive, and since I subscribe to factual relativism, you are just as alive as you are dead!"
Early submarines had to be diesel powered, because that's all we had at the time, then as soon as we invented power that didn't need to breathe air (nuclear), we made nuclear subs. Subs today are nuclear. We're not stupid. Similarly, it doesn't take a genius to design aquatic creatures with gills, not lungs. Evolution shows why whales are air breathing, while creationism instead makes it look like God is incompetent.
I can just imagine what an engineer may say, after he routed the phosphine degasser through the office space, killing everyone:
"Oh, that design of the phosphine degasser? That's as good as any other design, it's just your opinion that it's worse, and in my opinion, it's fine."
Please don't misrepresent what I say. I say that God is so incredible a creator that he can create a creation which itself has the ability to fill in the details, so God need not be a micromanager. Thus God is no more to blame for the many incompetent designs we see than God is to blame when I make a mistake. I don't see how acknowledging that some of God's creations, such as evoluiton or such as me, can make mistakes, in any way is calling someone else (God) incompetent.
So because you ascribe to seeing God as a micro-manager, who fills in every detail of creation, you have to respond to the obvious and undeniable stupid designs in nature by denying not only that they are stupid designs, but that anything is objectively better than anything else. You go past moral relativism even to the point of factual relativism, the idea that we all have our own truth, and that all truths are equally true.
