Threaded headsets do seem to be going the way of the cotter pin.
For me the big advantage of the new type is that it is two screws clamping the bars on, which allows you to whip the bars off without taking all the tape off and sliding them out of the slit-it-and-nip-it arrangement. This isn't per se inherent in the bearing design and could have been an improved version of the old type.
Supposedly the bearing arrangement is an improvement. Don't think there's much in it regarding ease of adjustment (of the bearings that is). The new type are more of a pain to adjust heigh wise, and have limited scope for raising them again once they are set for a given rider, and are ugly, perhaps even a hazard if left with too much spare stem.
