Which is the best Spitfire mark?
The one that just shot the Bf 109 off of my tail.

Every 'Best' question needs
to be qualified, when and where.
1. The Mk.I because it was there first.
2. The Mk.II because it was there with the improvements needed.
3. The Mk.V because it more than just became a stopgap and gave hope.
4. The Mk.IX because it gave the Allies the only actual true equal balance in 1942.
5. The Mk.VIII because it took that balance that the IX gave and improved on it
in spades making it useful in the Pacific.
6. The Mk.XII because it had the low performance when needed.
7. The Mk.XIV because its speed allowed it to more than just compete, it set the
Standard. It lost some of the magnificent handling attributes of the Mk.V / IX but its
performance allowed it to set the standard that all other fighter aircraft would be
judge by. Much like comparing the handling of the P-40 against the P-51 Merlins.
