I'd go with Nagilum. Why? It'd be harsh, but we'd advance alright. I'd think he'd have a viewpoint not unlike the Shadows in Bab-5: evolve through conflict, or die. I like that.
Okay then, why don't you transfer over to the mirror universe where you get exactly this "survival of the strongest" and "evolution through conflict"?
Just make sure that while you stab your superior officer in the back, somebody else is watching yours.
B5 addresses issues of being. Will you go through life with an egotistical social Darwinist attitude and a "dog eats dog" mentality, be herded around like a cattle of sheep because your government knows best or do something else and act and live differently?

B5 also addresses issues of order and chaos, and which is more productive. And I would call it a big mistake to claim that the show judges one superior to the other.
Look Bob, this is the god I'd choose, and I'd choose the Shadows in a heartbeat over the Vorlons. You can apply all the negatively freighted adjectives you like, because somehow my choice gets your dander up, but your choice of words won't change what I've chosen into what you
imagine it is inside your own head.
Interesting that you'd select
social Darwinism as an inherently pejorative phrase to apply to my selection here--I was thinking more of actual, genuine,
biological change, through a very sophisticated form of breeding program. I'm sure I don't have to explain to you that modern ev. theory is far more than Darwinism. Neither Darwinism in any form nor modern evolutionary theory applies to the OP's question, as both are entirely undirected/nonteleological.
The mirror universe would not give me what I'm talking about here, because there is no guidance/control (as far as we know). Your stab-in-the-back paradigm is chaos without direction. No Nagilum or Shadows shaping species. That's what I wanted.
Why don't you propose an alternative answer? Not a "no God"-type equivocation, but an answer derived from Trek canon. And tell me why your choice would be better than Nagilum.
