The full answer depends on where you are riding, how you are riding, and the conditions you are riding in. Windy, winding, hilly courses that you tackle on a road bike with some friends would have me leaning towards a less deep set of wheels. A flat calm straight triathlon course on a tri-bike I'd want more depth.
With the wheels you are looking at, and the price range you are looking at, you aren't going to be getting into the newer shaped wheels (like the Zipp Firecrest and other similarly shaped wheels) that work especially well in cross winds...which means the depth will come into play if you are in a windy situation.
My bottom line would be go with shallower wheels unless you have hard reason to go deep. The slight aero benefit of the deeper wheels will be outweighed by the greater versatility of the shallower ones. With the exception of the latest tech in wheels (Firecrest shape) my #1 criteria is hubs...a great hub on a so-so rim is much better than a so-so hub on a great rim...keep that in mind when making final decision.
If possible, ride on a set of the wheels. Find a friend that has a set identical or similar to the ones you are thinking about and take them on a typical ride (not just a ten minute test).
Also: I've been recommending folks to consider semi-carbon (carbon with alloy braking surface). These are a bit heavier, but not much and you won't have to change brake pads moving back and forth.
Have fun, be safe.
