You are suggesting a competition where the F-35 has to perform the other aircraft’s primary mission. So how about a competition between the F-22, A-10, and the F-35, where the mission is deep strike against a heavily defended target that requires 2,000 pound class weapons for destruction?
Touche.
Yes; after all the F-35 is being labeled as a "do everything [better]" airframe.

The F-22 and A-10 don't make any pretenses to being for that sort of mission, they're for air-superiority and close-air-support, respectively.
