Its statistical record? Go look at the chart that Lusche posted earlier in this thread. Fewer people fly the HurriC than fly the 109K, and it has a comparatively lower K/D ratio. The N1K has a lower K/D too, though more people fly it than the 109K. The Spit VIII, Spit IX, Seafire and Spit V, all sporting the uber Hispanos, see lower usage and possess lower K/D ratios than the 109K.
I get what you're trying to say, but you can't quantify it. The statistical record doesn't support your claim.
The 109K4(And the 38) crowd is generally more skilled than the Spit/N1k crowd, which explains the discrepancy in K/D. The 109K4 popularity has certainly increased the past year, year and a half, but it is flown by a more advanced player which is where the statistical discrepancies lie.
Those statistics however, do not paint a clear picture, because if you took the entire K4 community, put them in Spit8's/Spit16's, and the entire Spit8/Spit16 community and put them in K4s, the stats would be something entirely different. The Spits would have
incredibly dominating statistics. This obviously cannot be proven because God knows the K4 community does not want to fly spits and God knows the spitfire community
cannot fly K4s, but any vet knows this to be accurate. (And before The Few come in and defend the spit and their undisputed skill, there are exceptions to this glaringly obvious point I am making)
Fact of the matter is, noobs generally fly spits, 51ds, n1ks, and hurrics. Noobs generally do not fly 109s. That is the only metric you need to measure what the EZ planes are.
