I'm quite sure others have said this many times over (probably even me somewhere in this thread): there is no more capable aircraft than the Spit16. The only real weakness is its ability to keep up in a fast dive of the those aircraft who run best while besting the bulk of the aircraft out there in a dogfight.
Its turns very well; it rolls very well; it climbs very well; it accelerates very well; it has more than enough firepower; it carries 1k worth of ord (3 dead gv's); it has great visibility; and has above average speed, and it holds E extremely well. If it is anywhere near the "speed demons" at the start of a sprintor run-a-thon the runner is dead meat.
There are planes with less across the board abilities but are perked, the Spit14 comes to mind right away. The Spit14 has a wee bit a speed and a wee bit a climb advantage over the Spit16. If anything, the Spit 16 should have a small perk (?), and the Spit 14 should have lessor than it had now (down to a 7?)
