Hit has probably the shittiest timestop of them all. Dude can't stop for more than a second. Between DIO and Guldo it's a toss up but I'm leaning towards DIO, not to mention Za Warudo can't be seen by the other two. Though Guldo makes up for having other abilities like telekinesis.
However, Hit has the ability to improve as he fights, so given enough time, He'll win the fight.
If all the characters play it smart, then I'm gonna give it to Guldo. Telekinesis, stop the other two, and slash their throat using a tree. Or Hit. I can't see DIO winning, he might be able to kill Guldo but he'll def lose against Hit imo
