So, what are you ?
A - pilot who flies for fun. He doesn't care what plane he flies, as long as he can find a fight and have a good time. Flies all the planes, no matter how competitive they are. (also type who crashes his plane to the ground when wife calls

)
Other reasons for this pilot might be: interested in WW2 planes in general, testing different types, racking score so he can prove underdogs are in fact competitive (you know who you are

)
B - pilot who, similar to A, flies for fun, but concentrates on one particular type, no matter how good or bad it is. Changes his ride of choice only after few months.
C - pilot who flies only the best plane available and switches it with every new release to stay competitive. Country or year are not important.
D - pilot that flies all types of one particular country. Switches plane types for different missions, but never the country.
E - pilot that flies only one type of one particular country. Almost never switches, regardless of version.
I'd go with E for me.
And you ?
