I believe that Quanchi's argument is that Khan's uber-weapon, which can destroy entire ships, is too powerful for Vader to block as he did with Han's simple blaster bolt, and that Vader doesn't have the reflexes to Force-grab the uber-weapon (or TK-effect Khan in some other way) before Khan shoots him. And I'm pretty sure a blast that can obliterate starships can't be blocked by a lightsaber.The argument makes sense. It can probably be refuted if someone can post the evidence, but it is definitely plausible.
