OP verse is quite high power wise. Guts is great and really powerful for his verse, but in one piece the speed is different and the strength is different. There are dozen of exemple of people weaker than Kyros who have great feats strength or speed.
Diamante can do that
And Kyros can do that
Kyros can beat a giant, a Fishman underwater without a single wound etc.
Kyros is faster and stronger and more durable.
