I`m not sure. JSF isnt near from finish yet, and we dont know enough, or have the toys to simulate/conclude. But as most questions here, we all pretend to know a lot more than those who have an different opinion than ourself. Nationalism seems to be the key factor when it comes down to a choice. I see many good points on both sides. BTW Im new here, and Im from Norway. Hence my bad english. Keep up the good guesswork. Its quite interesting to read. I would guess that they are equals. ET is probably best suited for Air Supiority missons, and crusemissile defense/attack, just as the awsome Raptor. While JSF is better suited for close air support. I realy like the UKs mix of them(and US mix f22/35). Thats an impessive of a airdefence. Wish Norway could do that.
