Nothing wrong with CXP33's - my fixed has them and I've had some old 7400 Dura Ace hubs re-built into CXP33's - very good rims, certainly not uncomfortable, and the aero profile is just literally a few mm more than an open pro...they are not deep. Very easy to clean though. CXP's are a bit heavier than Open Pro's, but I like the look and they are bullet proof.
The fixed rims have been bashed and are 100% fine - same with the others, although mine were built by my local LBS.
Both very good rims...just personal choice on the looks.
