The Hawker Hurricane was used against the bomber formations, the Spitfire went toe to toe with the ME 109’s, not exactly apples to apples comparison.
Weren’t the German bombers protected by the ME 109s? They flew their Hawkers, and later their Spitfires, to destroy any German plane they could find.
