Just couple general comments regarding Soviet first line fighters. Imowface, I hope you don't mind.
Eastern front was the longest landfront of the war and over it raged a huge air war. Very different from the air war in the western front but just as big, if not bigger in many instances. Lavochkin, Yak-1/3 and Yak-7/9 series of fighters were just as important for the VVS as the P-38, P-47 and P-51 series of fighters were for the USAAF. Right now, we have 10 aircraft covering those USAAF fighters and only 4 covering those VVS fighters. And, two those Soviet fighters AHII has are "late-in-the-war" somewhat unrepresentive examples of the total production. I don't think anyone could imagine a situation where AHII would still totally miss one of the 3 major USAAF ETO-fighters while having only 4 variants to divide between the two that AHII actually would have!! That is the situation where these VVS fighters are in right now. We have none from the Yak-1/3 -series and have only two variants per series for the other two. And they saw MASSIVE amounts of action more or less right from the start of Great Patriotic War (starting with Yak-1 and LaGG-1) to the end and were produced in tens of thousands.
La-5 is for the La-5FN, in many ways, what P-38G is to the P-38J. More powerful engines slightly higher wingloading and their operational debuts are one year apart.
