CM,
F-22 is purely air-to-air and, as such, faces vastly different threats and has the option to engage, disengage and re-engage depending on the tactical situation and threat, making maximum use of its stealth model.
F-22 is not purely A-A. The mantra was once, "not a pound for air-to-ground" but F-22 has had JDAM and SDB capability for some time now.
I agree with those who have posted that, on the subject of RCS, it "depends." It always gives me a wry smile when stealth seems the be the only thing people care about; it is but one part of the system after all.
Anyway, good to see the debate continues to rage.
