The cute splatling hug

On a similar note, I've fallen in love with the Splat Dualie post-battle animations for Splatoon 2.
(They, along with the other victory/defeat weapon animations for Splatoon 2, can be seen here.)

The Dualies animation is pretty great. Boy looks cool doing those moves and the girl looks cute and hyped swinging her hips.

Any animation that has to with the inklings being happy is the best animations

I actually kinda like the "thats what happens when you all clump together and they throw a disruptor" look of a roller's losing animation
and the slosher hitting your head losing animation =p

I recommend using the hydra splatling with the sprinkler, it is awesome with squidparties, and damage up gear a sprinkler can be unstoppable!
