Aero and power gurus, I need your input on frame choices

Hi-
I am looking at getting a new TT bike. I’m 5’9’’ and I need something with a top tube that is shorter than 52cm, yet still uses 700c wheels.

I am considering the following and I’d like information about why I should or should not choose one make over another:

  1. 2012 Ridley Dean

  2. 2011 QR Cd0.1

  3. 2010 Kuota Queen K

One thing in particular that I’d like addressed is the influence/affect of an angled chain stays and the purported seat tube angle that is increased based on the angle between the chain stays and the seat tube. Also, feel free to compare other frames that are not mentioned here, but the super bikes are beyond what I’m willing to spend b/c I’m merely an AG’er with several other hobbies.

Fit first. Second is the bike you like the most. I believe there isn’t much if any real world difference in speed and aero ness with you, the rider, on the bike.
