Pucci doesn't speak or react any faster than a normal Stand User, so I'm relatively certain it's only his body that's sped up, and not his mind. Made in Heaven does speed up the rate at which time related abilities pass but also keep in mind that Star Platinum was fast enough that, even with the shortened time stop, he still could've hit Pucci if he hadn't had to protect Jolyne. And King Crimson's ability lasts twice as long as Star Platinum's time stop, so I think it's reasonable that Diavolo could hit him.

But yes, the best Stand for defeating King Crimson is something that is immensely powerful but also doesn't put the user at risk, which really limits it to top-tier long distance types like Red Hot Chili Peppers or Tusk ACT 4. Weather Report is technically a close range type but I'd reckon it's range is still good enough to do the trick.

Man in the Mirror and C-Moon are in the maybe pile. They both only require one brief moment to grab/hit Diavolo and they win, but considering King Crimson is notably faster than either of those Stands and Diavolo using Epitaph, it'd be difficult for them.
