To me the biggest one is the seizing issue. An engineering solution which removes the possibility of seizing is in my mind superior. Easily installing and uninstalling cockpit parts is a bonus.
If you change handlebar heights enough, seizing simply isn't an issue. In the long run, time spent messing with headset adjustment swings in favor of threaded. And roadside stem height changes are trivial. (You might need to tap the allen key with a rock.)

Currently my only threadless bike is unridable because I ruined the star nut adjusting the headset. (As far as I can tell, they die after so many stem swaps. In other words they are a consumable. I've been neglecting to stock up. Maybe I am just a hack with them. Maybe a really good thing that I have never attempted an on-road height adjust.)
