I think it's a personal call. Both are abhorrent, but I go for the patdown because the health risks are less, the Nude-o-Scopes exemplify government waste and corruption, the patdown doesn't generate electronic images of my naked body that can be saved, the patdown gives TSA fewer details about anything I am concealing, the patdown forces TSA staff to be uncomfortable, and I know exactly who is assaulting me (as opposed to the anonymous viewer of Nude-o-Scope images).
