Carbon will allow you to build a much lighter frame than you can with aluminum. However as you saw the Domane was 20lbs. Pretty heavy for a carbon bike these days.
Ride characteristics are similar enough between the two. But I only ride steel bikes, so I'm only relating what I've read and remembered.
