Cons

MPlayerX creshes occur more often than in usual video players. They should be tackled properly.
Con High CPU usage is possible
Sometimes after the player or OS X update file reproduction can demand a significant part of CPU usage
Con No proper playlist feature
In spite of easy and comfy smart-play, in general playlist isn’t user friendly
Con No retina display support on old OSX
MPlayerX does not support retina display on OS X older than Mountain Lion, but amount of Mac’s with older OS X are quite rare nowadays
Con Minimal theme support
Con Lack of a typical GUI can be jarring to some
The minimal interface comes at the cost of beginner-friendliness. You need to know keyboard shortcuts by heart, settings are set in text files, right-clicking won't bring up a menu, etc.
