I believe this may be conventional wisdom but time-nuts shouldn't believe
conventional wisdom they should be measuring.
E.g. FSM says their NTP+PTP "servers" perform equally well using either
protocol.  The trick is to use optimized NTP software and timestamping

Or, to rephrase "equally poorly using either protocol".
