Well, that was easily won. I do agree with Lightning though, the Hurricane was the more important of the two but the Spitfire was the better fighter. There were the 32 squadrons of Hurricane and 11 squadrons of Spitfire in the BoB, numbers were another factor of their success. Hurricanes also had the ease of build as one over on the Spitfire.
Even with that the Hurricane could tangle with the Bf-109 perfectly well, Hurricanes were credited with several 109 kills.
The Hurricane was easier to fly, but the Spitfire with a veteran at the controls was much more deadly than any other fighter of the war (I'm refering to late marks mostly here).
