It is all about pilot, that is why i can be on the WW2 server and be in a really bad place against 2 or 3 Human flyers and still come out with my arse in tact.......
With the Spitfire mk IX, you need to realize that in climbing it can beat a P-51D mustang, which is not to shaby. So it will really matter who the pilot is and if they and how they use their aircraft to it's strength and exploit E/A weaknesses..
