Since this is WW -- the Aquilo will be 300g-350g heavier. So if weight is a concern then the answer is obvious. The CAAD10 will have a slightly advantage in stiffness as well.
That said, the Aquilo is a very well built frame and IMHO no stable is complete without a ti rig.
Based on CAAD10's weight, it's hard to avoid butted sections with around 0.7-0.8mm of wall thickness (hopefully someone will have actual numbers). So the Aquilo's .9 wall thickness, but in titanium, is a lot more dent-resistent. And ti doesn't really fatigue and is more comfy.
Depending on your priorities, I feel this should be an easy decision.
