Since Luffy (almost) always has the main fight each arc, his fights are also the climax of that arc. All other fights are, considering the narrative, building to the climax and thus less spectectular. Ennies Lobby arc still managed to let each strawhat shine in their fight, so maybe Oda can pull that off again. I kinad doubt that thought, since Wano has way more characters, so I fear some of them are bound to dissapoint.
My bets are:
Will not dissapoint:
Luffy and his opponent(s), King, Queen, Strawhats that get a 1-on-1 (I expect each strawhat to get a fight, everything else would be dissapointing to me)
Will probably dissapoint:
Scabbards, Flying six, Numbers, Kaido Jr.
