Tbh having a goofy Yonko going at it with the character with the most trollish personality had the potential to make for a fun and unique fight. Kizaru's reaction to getting thrown into the sea got a chuckle out of me so that's something at least...
Overall though yeah this wasn't the long awaited Yonko vs Admiral 1v1 showdown that people were expecting. Never had the vibe of a main confrontation with how much of it was off panel or ugly generic clashing (like what is even going on here). With Saturn in the spotlight and how much this flashback is building up Luffy stepping in to confront him as Nika, I doubt this fight will even continue. We will see tho...

However it seems to me like Oda deliberately opted to have them primarily play a game of cat and mouse because one side was seemingly more immediately powerful than the other and had to hold off on a proper fight for plot reasons. And like you said, the flashback content building up the importance of Nika/Luffy in relation to Bonney and Kuma certainly suggests that Luffy will be switching focus over to fighting Saturn once the flashbacks are over and he's back on his feet again.
