Kakshi didnt need his Sharingan to follow Lee. Everyone was watching that fight. He was using using its ability to see chakra flow and see more clearly, but even Gaara, probably the slowest person in the room, was able to see and counter Lee during his split second flinch.

Minato was noted by the other kage for his speed and Shunshin upon their arrival so there isnt much reason to believe he used anything else.

In the manga Minato threw his kunai sometime right before A was milimeters from his face. We know he has faster reaction time than max speed A but that doesnt translate to travel speed.

We have no real way to determine who has the better footspeed because A has never run a long distance like Minato has.
