I try to stay out of the MCU vs. FOX X-Men debates about accurate Quicksilvers, but the FOX version is not comic accurate. He'd never be able to outrun bullets like they're standing still - at best, based on his top speed, he might be able to reach one or two bullets if trying to catch/deflect them, so the MCU depiction is more consistent. I think without the Speed Force, Flash moves at around Mach 2.
