The IL2 is better than I have read claimed here, I can't believe how played down Russia's most famous and formidable foe Sturmovik is being marginalised to fit the notion its monumentally worse than a 190F8 and that fixes everything. The job they are to do is object killing, and if I wanted the path of least resistance I'd choose an IL2 over the 190F8 for the job, especially in squadron strength.
I've flown lots of scenario missions in Il-2's and scenario missions in jabo 190A's (quite similar to 190F's) and have been a GL of groups of both types. The 190 is vastly superior to the Il-2. In fact, in this scenario, you can see that by actual testing and results.
In this scenario, the 190F compared to the Il-2:
-- can kill as many or more objects (you can test this offline)
-- can kill more objects in the presence of enemy fighters before dying
-- is more than 100 mph faster
-- has a vastly better roll rate
-- climbs more than 1000 fpm faster
-- has 67% more cannon rounds
The Il-2 in AH is a little sturdier than the 190F, but not enormously so. It is quite readily shot down by the likes of 109G's, let alone 190's, as you can see from my films of getting shot down.
If you were my CO and had the choice of the two types, as an experienced ground-attack group leader who has lead groups of both types, I would strongly advise you to take the jabo 190's.
