Was Ulti alone ?
Why Ulti could catch Luffy ?
Because he put P1 down. How she will catch him in a 1vs1 if P1 isn't there?
Luffy is faster and have FS
It's not because he needed G4 for a specific situation that he will need it for the entire fight against Ulti

Even with his FS Ulti still send him flying and bleeding with her headbutt
Luffy did need G4 and try to use it, if Yamato didn't try to save him he would have used G4 stop your delusional mental gymnastics already!
The point is you already admitted that base Luffy can beat King but Luffy needed G4 for Ulti, so Ulti > King
