There was an assessment a while back with kill ratios - how many bandits you could kill for the loss of your jet. I can't remember the absolute figures but the F22 was way ahead. The Typhoon was something like 5:1, the Rafael was, IIRC but I stand to be corrected, 1.6:1.
No match really. The study which was recent did not, again IIRC, include JSF but if it had it would presumably be like including Harrier in the fight evaluation.
There is the other old saw, you can make a bomber out of a fighter but not a fighter out of a bomber - Hurricane, Mosquito, Hunter, F3. You might suggest that the FA2 disproves that theory or that the FA2 was really a different design from a Harrier GR.
