I don't think we'll ever get a solid comparison test with anything unless it comes from someone outside of the industry and any media tied to it, such as what was done with FrictionFacts.
Windtunnel testing is particularly expensive, and even when some media outlets choose that method for wheels/frames/whatever, some brands do not lend their wheels for testing (for one reason or another), and there may already be an ulterior bias due to advertising or nationality of origin, etc:. A lot of 'personal variables' come into play, unfortunately.
It would be a beautiful day when there is a patron wealthy enough (and passionate enough) to use windtunnel & staffing time to test independently purchased products from all relevant manufacturers, not just the big names.
For example with wheels: wouldn't it be great to see how the newer Open Mould "wide aero" compared to November's Rail, Boyd's new wheels, Flo, ZIPP, Enve, Reynolds, CarbonSports, Xentis, Easton and others? Instead with magazine testing we only hear about the 'big names'.
