Well, when try both you can make an informed comparison!
One recommendation (if it's not the default in the Meinberg
implementation) is to add the -M (I think) parameter to the program's
"Path to executable" so that the multi-media timers are permanently
enabled. This made a significant improvement to short-term stability, as
Richard mentioned. Please check the documentation for details.
