Sustained turn rate is of course quite another matter. This is dependent on the thrust used and the induced drag present at the conditions where it is measured. Since we don’t know those details it is quite possible that there are circumstances where they are in favour of the F35 (and others where they are not!)
Hmmm. Sustained turn rate of F-35 is 4.5G, about the same as F-16 and F-18.
