What are your goals? NTP server? Neat graphs? The Pi 3 has Ethernet on USB. That adds a layer of jitter to packet timings so a Pi 3 even with GPS will never make a great NTP server. How stable is your temperature? Self heating as the CPU load changes is important even if the room temperature is stable. A TCXO won't help if the temperature is already stable. If you have 2 identical Pi-s, you could put the TCXO on one and run a side-by-side comparison and tell us what happens. -- These are my opinions.
