Stack and reach measurements are your friend. Do you have a road bike that fits? Can you get the stack and reach for it? If you can, compare them to the crossers.
As a general rule, the crosser stack should be a bit taller and the reach a touch shorter.
I suspect the Vapour is a touch racier than the CAAD but I haven't compared their geos. I think the vapour might have a tapered fork, too - the front end will likely be a bit stiffer. But I haven't ridden it so who knows.
