It's a little hard to say.
The rooftop fight is firing on all cylinders. Quite literally the best One Piece content since the Time Skip and the best One Piece part since Marineford War. If this part keeps up, we might end up getting the best fight of the series so far.
Anything below the rooftop is underwhelming, UNLESS something badass is happening (Zoro loldiffing Apoo, Franky vs Sasaki, etc). So, I guess, anything below the rooftop will start looking up (pun intended) when the undercard matches begin to take place one by one.
