Both great fights.  The execution by both the writing team and the animators was top tier.  I think the animation on the Vi vs Jinx fight  was great but the lazy way they created the Vi Caitlyn conflict was weak.

Jinx vs ekko is S tier to be sure and my favorite of the series as well.  If you haven't seen Naruto and have no desire to.  The Obito vs Kakashi fight is similar.  You will miss out on the writing that makes it good but the animation is smooth AF.
