I think a big issue comes from the fact that unlike Pre Timeskip. You don't have fighters like Perona or Mr 4 anymore. Fighters that the weaker trio can defeat due to matchup
Instead we are entering the New World where everyone is either a Haki user or at least good in Hand to Hand combat...
With the exception of Maybe Bege. Most Supernovas are Above Flying Six/Big Mom Veterans
I don't think Urouge is above Hawkins Killer or Drake by a Large Margin. It's just that by the time of Fishman island or so. Most Supernovas surpassed that level
Queen's Neck is tough enough to knock him out by accident. Sanji is clashing with that Neck
Just like how base Neko/Inu are above Sulong Shishilian/Pedro because one was overwhelmed by Jack's Trunk and the others either blocked or Overpowered it.
Sanji Mauls Perospero without the Raid...
I am kinda hoping he lets those three have a more varied Moveset compared to Ulti and Page One. Especially when they are swordmen with Maria even Having Webs and WsW and Sasaki Possibly having Meito
At least Page One and Ulti being One Dimensional is kinda Understandable since they are Young...
I think it's that Oda focuses on different things in fights these days. Instead of strategy and several moves. We have Characters doing the same thing over and over again while having inner monologue
Luffy fights are the exception to this
