Earlier quoted context omitted.
A lot of highly qualified people who have flown it say otherwise. https://www.airspacemag.com/military-aviation/f-35-faces-mos... Chip Berke is an F22 and F35 test pilot, and the first F35 Squadron commander. He's probably the most qualified person on the planet to talk about fifth gen aircraft: https://www.youtube.com/watch?v=zxK6O5--9Z0&t=203s
Admittedly my sample size is 1 so I'm not pretending my anecdata is conclusive, but you have to be wary of what people will say publicly about politically motivated projects. EDIT: Although to be fair, I wrote that before looking at your links, I feel like that context is important (although I stand by my statement).
The F35 has been badly politicized, but it has also been the victim of an absolute shitload of criticism from people who want it to be something it was never intended to be and are unhappy that the F22 was cancelled early.
If it were just that Colonel Berke liked the plane, it would be one thing. He really explains it in detail in the video. I'll admit I wasn't quite sold on the the plane years ago, but once I saw this video it pretty thoroughly changed my mind.
I realize the video is a bit long, and I almost never post links to videos -- but this one is well worth the watch.
