Bf 109E is/was vastly better than any Yak fighter since it was available for two years when Yak fighters were not available - 1939 to 1940.
By that logic the Gloster Gladiator is better than both... when the Yak 1 and Yak 7 appeared on the battlefields in Russia bf 109E were still in use, albeit mostly relegated to Jabo formations and so on. Similarly when the Tomahawk appeared in North Africa, 109E were still around, 109F were brojught in to replace them but that was not an instant process. As far as performance goes, I think perhaps you are ignoring the later Yak 1B, Yak 7B etc.
Any model of P-40 and any Yak were competitive if the Bf 109s were at low-ish altitudes, no such luck above 3-4 km.
Yes - exactly- and what percentage of combats on the Russian Front, the only place where the Yak lived, took place above 3-4km?
Spitfire IX vs. Bf 109E? That is a joke. At low and medium altitudes Spitfire IX have had performance parity vs. German opposition, it edged them out above 25000 ft, bar the 109s with AS engine and DB 605D (in the 109G-10s and K-4s mostly).
When the Spit IX was deployed in North Africa in 1942 there were still Bf 109E equipping squadrons, with plenty of 109F and a good number of G-2 and G-4, and some G-6 in 1943. The Spit IX squadrons wrought havoc against them all.
This is not borne out in the combat record over North Africa or Malta.The 109F-4 was with clear edge vs any Mk.V,
Per Shores Mediterranean Air War series, the Spit Vc was out-fighting 109F and G2, and the Spit IX was dominating them.
