Misconception: Minato barely reacted to Raikage's speed
You say he barely reacted? It is actually far from the truth. It's even in fact the contrary. It's the Raikage the one who couldn't handle Minato's speed(Raikage was still on Minato's first position when Minato did 3actions: throw a kunai, teleport away and come back on Raikage).
At that particular moment, Minato's goal wasn't to dodge the attack only, but to dodge it
after preparing his counter-attack, reason why he threw a kunai above him. If he had time to throw a kunai above him
AND teleport away(so 2 actions) when Raikage was inches away from him, that already shows he could have dodge it long before if he really wanted, but like i've said, it wasn't his goal at all
If Minato was able to do all that in that mere fraction of seconds, it's enough for me to realise that Minato's reaction speed is above that of V2 Raikage
You can even notice that on the action later,
while turning his back, while Raikage was starting his attack-speed,

You can laugh all what you want but feats and hype puts Minato at the top. On the contrary of "Mr can't control his speed", Minato can travel fast and control his momentum
