Warcury, V. Nusjuro and Mars kinda come off as most impressive this arc from the perspective of either strength or ability to get things done.
Saturn and Ju Peter come after though Saturn kinda had it coming against Kuma to allow him a cathartic moment to unleash all his anger, and kinda jobbed for a bit. At least he had some strong attacks, and kept coming back. Ju Peter came back from decapitation, but just sucking stuff up, which albeit was hype considering how strong he is and affecting the ships, got boring when everyone else was busy.
At least they accomplished their goal and didn't let everything out, but man Vegapunk did good in revealing a lot to the world.
