To be honest - I have the same opinion, but I cant figure out why.
I have trashed 2 sets (on the road). I know three guys who have a had problems with them on the road. There is no way I would ever use a set of nuevations for cross. I gave my 3rd set to my wife for the road but she only weighs 120 lbs.
I trained on Aero4s for road all summer and spring and they held up perfect. I'll be racing CX on them as well. I've already ridden some singletrack and general CX drills/training and they're doing great. Anyways, for ~$230 who cares, just run em till they're dead and get a new set.
