I am rather certain the F-35 is a high zoot ride already, the Avionics are beyond state of the art, and no doubt the radar is awesome. The Joint in JSF means that everyone will be free to adapt their own equipment into and onto the F-35, it is a user friendly system. The F-22 not so much, but it is much more difficult to hack or upgrade.
I was very impressed when the F-35 was flown to 73 degrees AoA, and watching them tossing it around with no need to deploy that spin chute is very confidence inspiring. It has now been to 110 degrees and recovered without incident. So Yes, I have been converted, and yes it will be a fabulous little sister to the Raptor, heck, its will be a fabulous airplane on its own terms, I could prolly land the B in my double lot next to my house. It is a very nice airplane to fly, predictable, and linear thanks to that kool FCS. and that friend is what it takes to win, the airplane has to be "intuitive", so that you may concentrate on deploying your weapons against the bad guy.
Many of the F-35 pilots are former Raptor Men, they know "if" their are "chinks" in the Queen's armor, and they will exploit them to the max. There will be some F-35 victories over the F-22, I am certain that those eight F-35s operating as they have been designed to, with "situational awareness" will know ingress and egress routes and "set up" . They fact that the Raptor has "dominated" not only the F-15, F-16, F-18, but "all" foreign comers, tells how good she really is.
Those anecdotal "kills" by "guest" players in red-flags and little set-ups are "gimmes" to let the other team have a little fun, as the Raptor folks can't really find anyone on the home team to play their little games? So yes the F-35 is good in a much more generic way, and everybody will enjoy success in the F-35, it is a game changer. It will be just as deadly as the Raptor, and just as much fun to fly against "bad guys".
