It really depends on the use case.  chrony seems to pick a "best"
source and try really really hard to track that one true source.  ntpd
tries to intelligently track multiple sources at a time.

For a stratum 2/3 box that just tracks internet sources only, I've had
pretty good luck using chrony instead of ntpd.  For a stratum 1 box
that tracks a single GPS/PPS source, it probably would work great for
that too.  For a local stratum 2 that tracks just local stratum 1s,
that would probably be an excellent use case for ntpd.  For a local
stratum 3 that just tracks multiple local stratum 2s?  That would
probably be a good chrony use, as has temperature compensation.

It's hard to really be generic, this is one of those cases where
"test!" kind of applies.
