PTP is way better than NTP, but it might be possible that reference time is somehow taken from NTP anyway.

What I Mean:

Reference .gov atomic clock (not radium one) -> NTP -> ? -> ? -> satellite control station -> gps -> PTP

Hahaha

PTP is more precise so it's much harder to synchronize over long distances. Even in data centers it benefits from hop-by-hop participation from the routers involved.
