A properly trained WW2 aviator was the "right hands".
Or a good il2 pilot who actually thinks about survival, and knows team tactics(further than flying as just a pair). It has only adequate guns yep, but they are more than enough. Flown with some brains, it doesnt have to let anyone in the guns range, unless if bounced at low altitude.
I dont know how "the mods" model the Spitfire XIV, as far as I know, it traded some qualities for the low and medium altitude speed it gained with the Griffon engine...
The Spit IXc 25lbs is crap above medium alts too. HF IXe is usually much more useful.
