We use all the above, depending on the POP.
We've found they are all reliable as long as the GPS antenna is in a
decent location. We have one syncpipe that loses sync about once a
month, but we're certain it's because of the poor location we're using
for the GPS antenna.

TJ,
We’ve seen occasional issues with the ePMP APs in the field losing the
sync-over-power pulse from SyncInjectors and CTM-2Ms, and Cambium
responded to my trouble ticket with the following: “There has been
extensive discussion/testing here regarding supported/compatible third
party Sync/power sources for ePMP APs. We noticed sync compatibility
issues when using packetflux sync injectors.”
My advice is to deploy with the puck antenna and use it as your
primary sync source, and keep the SyncInjector oprerational as a
backup. The onboard GPS seems to be stable, and appears to be less
likely to make your customers call you complaining, “the Internet is
down!”
