From the ones that you mention, the QuickPro ER One is the only real aero frame in your list. The others are more allrounder frames. Not that they will be slow, but that one has more aero features that in theory will result in a frame with less drag.
To make the analogy with an SL8: it's definitely not the most aero bike, but it doesn't mean you will have a big disadvantage on the flats compared to other pure aero bikes. Similar here.
I would say, pick the one that you like the most.
