More class options > animated sex scenes.
This is a false dichotomy, because this is not an either or situation. They have already stated they will implement all of the classes and the sub classes within the PHB. It isn't done yet, but it will be on release. Even if this was not the case however, the people responsible for doing animations are not the people responsible for implementing classes, those are 2 completely different skill sets. Animators are not suddenly going to become programmers just because sex scenes are removed.
Personally, my bigger issue with romances is that they feel poorly written. The characters are written to be player-sexual, rather than having their own defined preferences. This makes them much more one dimensional than they could otherwise be and takes away from them as characters.
