Noise and mud. The Eagle CR makes less of the first and resists the second better if you're not using a retention device. Taller teeth. I can't speak to durability, I'm sure steel does have a leg up on that one. That Renthal CR is new to me. As above, Eagle cranksets tend to come with the ring, so the cost is baked-in.
I charted out the various crank arm combinations here, you might find it interesting:
