I think Haas concept looks far better. To have so many gills for cooling is not good for aero. Basic concept of Adrian Newey is to have tight rear and sloping engine cover. Aston Martin concept of huge undercat is far less stabile aero concept.
Yep, but that's for a flat floor. For a curved floor, with the venturi tunnels. Having undercut helps to emulate a second tier like situation. So air flowing under the floor and right above the floor will have a similar profile(Obviously different speed and potential energy and pressure diffrentials). So a undercut design is actually more stable for this generation of cars, but it causes more drag and higher centre of gravity and likely switch to pushrod rear suspension (renders still show pullrod, but I don't think so). But in exchange there will be a massive downforce advantage as well. Haas's tight coke bottle concept on the other hand, is less draggy and well it does give more room for air to flow to the back thus better control when it comes to the rear wings. The undercut floor though give more flow control tothe two large winglets below the rear wing. Basically, if all created equal with no flaws, expect the Haas to be faster in Monza, Austria and low drag tracks, and Aston to be faster in High-Medium downforce tracks
