Both are good planes, but I prefer the Spitfire... The Spitfire Mk. IX to be exact.
It had a great maneuvrability with a Merlin 61 V-12 engine, two 20 mm cannons and four 303 machines guns (plus two bomb racks for dive bombing). And it had the longest life of every WW II fighter (from 1942 until the end of the British decolonisation wars). And its looked great.
Oh, and the Mk. XIV was the best dogfighter of the war.
So the Spitfire was the best.
