Well, I can't vote, since 'other' is not an option. But There is a multitude and myriad of media players that you don't have listed.  I use FreeAmp mostly and Irfanview, they are fast and efficient, which is pre-requisite to dwell on my machine.
I would never consider using any of the ones you listed. WMP is a bloated piece of crap, and so is RealPlayer, both try to hog and take over all your media files.
So to each his own ? Remember, my quick tempered responce here is aimed at the players you listed, not at your poll !
