MusE is quite good at syncing to external midi clock input. 
It is guaranteed not to drift, should be rock solid no matter what you 
 throw at it.
It supports midi realtime and MMC commands.
But it does not sync to MTC yet. 
Recently the ability to record the external tempos has been added.

Midi sync clock output on the other hand, is a bit weaker at the moment.
It should work, but sync output needs some fixing for accuracy and timing,
 best results may be with the ALSA devices instead of Jack midi devices.

As the other posters say, Jack does not do syncing by itself.
It is up to the applications to do that.

Just ask if you need any help, our Sync Settings dialog may seem
 a bit overwhelming.
