To be honest, I don't know Cheetah's top speed or if she's proficcient in using it. But from what I've seen, she took it to Flash pretty badly.
Though Quicksilver doesn't even know his peak speed anymore now that he was exposed to Isotope E. He's hitting past Mach 10 now (which I know is nowhere near Flash, just saying), and he hasn't even reached his limit yet.
But yea, Cheetah still pretty much takes them out basically everytime.

Yeah but there two it hard to believe she could beat both at the same time.
Yea. If she's fast enough to give Flash problems, then she takes them both down pretty quickly.
