I use JR and have for years. For me, it comes down to user-interface and scale - JR has a really flexible, intuitive interface that allows me to easily navigate in any way I find convenient. It also handles 70K songs, which I found really strangled other players.
I'm not much on trying to compare the sound quality - I figure that a lossless compression directly output (ie, no O/S manipulation) is going to be near identical, if not identical, regardless of player.
