This looks pretty normal, though I'd probably remove the 'prefer' statement
(with lack of a reason not to) and the local clock statement, which does
more harm than good quite often (I believe to have observed that the sync to
UTC is lost faster when the link to the NTP servers is lost with an LCL
driver active, if the LCL isn't synched externally).

Are you sure 'netdate' which I don't know, uses NTP? I only know of
