I'll just add another data point. After the release of VLC 2.0 I was slightly dissatisfied with the new interface on OS X and used the opportunity to try out a couple of alternative players. In the end I stuck with MPlayerX because of short startup time and the minimalistic interface. But it was only a short love affair. The keyboard controls are pretty much non-existent, it can't open DVD menus, it only shows half the available duration of some of my music DVD rips (dual-layer?!?) and I have some occasional weird timing issues with regard to subtitles (image and subtitles suddenly not in sync). In the end I returned to VLC and all of my issues disappeared.

So kudos to the VLC team for producing such a great product (despite some questionable interface decisions). I'll take a player which "just works" over the pretty and shiny competitors every day.
