I think the flip-tops release the pressure faster than caps. Flip tops open almost instantly around the entire perimeter. Caps are pried off; it is a tiny gap that gets larger. Sort of the difference between releasing the pressure of a balloon all at once by popping it, or pushing a pin through the base and letting the air out more slowly. Or like shaking a soda bottle, then opening the cap all at once or slowly easing it open.
