There are some things that PTP does better than NTP, but there are also things that NTP does better than PTP. This is why pairing PTP and NTP together gives you a result that is better than either of them alone. PTP makes a great Stratum 0 reference clock for NTP, which can then apply higher level protocols along with other information source inputs to synthesize a higher quality time source that can then be made publicly available. And this is also why the Network Time Foundation [1] publicly supports both protocols. Disclaimer: I've been a member and supporter of the public NTP project since 2003, as well as associated projects like the NTF. [1] https://nwtime.org/ https://nwtime.org/
