For my taste, the only flawlessly (!) attraktive Spitfires are the Mk. XIV (razorback and bubble canopy version) and, even more so,the Mk. 21/22 with its slightly different wings.
All others had some aesthetics deficiency in one way or the other, e.g. unattractive vertical stabilizer shapes, supercharger inlet directly behind (underneath) the propeller.
Most Merlin Spits look snub-nosed, especially the early variants, which sucked aesthetically, imHo. There you have it.
