I think it mostly matters what your goal is, as well as the environment of course. If your goal is to get out of the area as quickly as possible, then the back thrust kick or any kick that creates distance between you and the assailant is fine.
Otherwise, I'd go for whatever kick will most likely slip past his guard but which also ideally leads into my follow-up technique. The follow-up technique would most often be a hand combination because they can be rapid-fired faster and easier than the kick without leaving me standing on one leg.
This would probably necessitate me closing ground on the guy though as my first kick (unless a good snap or cutting kick) will send him some distance back. And, suddenly, we have a totally different situation than the cut-and-run scenario.
So, although I didn't even come close to answering what the better "stopping weapon" is, I don't think it can really be said for certainty because each kick has its own advantages. If I was pressed to say, any kick that takes advantage of hip torque should be better than those that don't so I'd go with Muy Tai kicks and thrust side kicks but one small flip kick to the groin can do wonders.
