WCI would have been better if Katakuri defeated Luffy and Luffy was forced to retreat while keeping Brulee hostage to justify Big Mom showing up on Wano to get Brulee back and free Her First Mate from the Mirror world
The overall theme of WCI is that the Strawhats get a humble pie and a glance of the gap between them and the Yonko crews. The problem is that that theme is Hugely undermined by Luffy defeating Katakuri. It only led to resentment from people who wanted Sanji Nami Chopper and Brook to have fights in that arc as Luffy got two fights while their favourite Strawhat didn't.

Zoro is the sole man to have sworn to never ever lose again. Kutakuri's defeat striked somewhat unnaturally contrived to me, mostly for the way Luffy could manage to overcome FS. Or like when Oda introduces new power ups too quickly..
