Whoever told you that is ignorant or an idiot. Add a gun pod and they are lethal in close quarters. Use their upgraded missiles, and close quarters does not happen.
Again, I think it was the wrong choice, but they are VERY lethal.

Here is another update. Apparently, the F-35 still loses sometimes, but that is improving. Good news. I have no desire for our side to lose.
