What unit from the Roman Army consisting of centuries enjoyed more prestige than the Roman navy?
Roman legion A Roman legion (from Latin "legio" "military levy, conscription", from "legere" "to choose") was the largest unit of the Roman army, evolving from 3000 men in early times to over 5200 men in imperial times, consisting of "centuries" as the basic units. Until the middle of the first century, 10 cohorts (about 5,000 men) made up a Roman Legion. This was later changed to nine cohorts of standard size (with 6 centuries at 80 men each) and one cohort, the first cohort, of double strength (5 double-strength centuries with 160 men each).
Sebastos Sebastos (Greek: σεβαστός "venerable one", pl. σεβαστοί, "sebastoi") was an honorific used by the ancient Greeks to render the Roman imperial title of "Augustus". The female form of the title was sebastē (σεβαστή). From the late 11th century on, during the Komnenian period, it and variants derived from it, like "sebastokrator", "protosebastos", "panhypersebastos", and "sebastohypertatos", formed the basis of a new system of court titles for the Byzantine Empire.
