I would say a more realistic comparison would be that an F-35 with external combat loads and therefore not that stealthy is equal to the F-16 with no real advantages.
Regardless, the flight performance of an F-35 is much better than an F-105 or F-4, that comparison is nuts! The F-35 is more maneuverable, has faster acceleration, has a tighter turning radius, etc. The F-22 is a much better pure fighter than an F-35 though of course.
That website seems to have a lot of asinine articles about the capabilities of modern U.S. aircraft. It even claims the 30 year old Su-27 is still the best fighter in the world, so I wouldn't give them much credibility.
