"The naval term would be "the pride of the fleet" or "the pride of the navy". The ship that wins all the awards for excellence and has for many years. I believe HMS Hood was considered the pride of the Royal Navy throughout the 20s and 30s.
The closest we got to this in TOS was in "The Immunity Syndrome" when Spock called the Enterprise the finest starship in the fleet."
Which then could explain that the title of "pride of the fleet" passed from Lexington
prior to TMP where Starfleet uniforms (e.g. Admiral Kirk) now wear the insignia of the Enterprise
placed in front of a circular insignia (another fine starship?). By the time of WOK it's again the insignia of Enterprise
placed in front of what could be a rectangular insignia.
