Why the Fleet Air Arm rejected the Brewster Buccaneer

Why did the Royal Navy reject the Brewster Buccaneer?

It did not fit the Fleet Air Arm's requirements or improve on the aircraft already serving its current missions.

The Fleet Air Arm rejected the Brewster Buccaneer because it did not fit the operational models and requirements then driving British naval aviation. Procurement depends on the fights a service expects to conduct, not on whether an aircraft is available for sale. The useful comparison is therefore between the Buccaneer and the aircraft already assigned to the Royal Navy's actual wartime tasks. Rejecting it does not mean every feature was worthless; it means another combination of aircraft and weapons served those roles better.
