Each jet in the game has it's own advantage, the j-10 is immune to missiles, the F-35 is the fastest jet in the game so long as you stratorun. I've gotten so good at stratorunning in the F-35 that I can't stand flying the sloppy ass J-10 anymore. The F-35 is so stable that it makes gunning down J-10s easy once you get behind em. And I don't even use a joystick, it's all keyboard for me (and I mean all keyboard, I don't use the mouse)
