Glad Rag,
It is a 7g airframe (yes 'g' available depends on load and height etc) and it certainly does have transonic acceleration capability. You are misinformed I'm afraid.
Stealth is not necessarily a one-trick pony either and, as you say, depends on who you are fighting. Out of a choice of every platform that the west will have in the next 20-30 years, not counting Raptor, I would go to war in F-35 every time.
Ironically, for your statement, F-35C has the worst transonic acceleration of all three variants.
