What earlier Sea Vixen and Buccaneer service could have changed

How would earlier service entry have changed the careers of British Cold War naval aircraft?

It could have strengthened carrier strike and all-weather defence sooner, but the early aircraft would be less capable than the mature versions eventually fielded.

Earlier entry into service creates a trade between time and maturity. An earlier Buccaneer would strengthen the Royal Navy's carrier strike arm. A Sea Vixen available during the Korean War could provide a formidable all-weather fighter capability for that period. Yet the prototype-era aircraft could not simply inherit every system and refinement of the version that entered service near 1960, so the counterfactual must account for a less mature design.
