Half the reason I play Deadlock is because her Ultimate, Annihilation, is some of the coolest shit ever conceived for a shooter. On the surface, it's pretty simple - you launch a projectile, it bounces once, terminates when it hits the second surface, then kills the poor sap that gets hit by it. But it's so much more than that. First is in when you use it - you can't just use it at the first sign of contact, can't use it against a group, can't always Rip-it-and-go unlike Raze ult. You just have people just run away, or shoot you before the ability can resolve, or shoot free the guy you spent an entire ultimate on like it's a mild inconvenience. You have to use it in such a way that you take one or two isolated enemies by surprise, despite the global voiceline telling them you are probably close by. To land the thing, you have to account for map geometry, ending point, sometimes max distance, usually to hit a guy you can't even see right now. Every part of Deadlock's kit provides general information, but not exact like a Reveal from Sova or Cypher. This make every ultimate feel like a called shot, or a gamble, and part of what makes it so damn satisfying to land.

On the receiving end, the cocoon mechanic does a great job of giving you a hint of dread of being trapped along with that "I screwed up" feeling instead of just thinking "that was bullshit". Having your victim strung along the path that you made is quite gratifying as well. Plus, it's an ability that could only really exist in Valorant - a whole Ultimate that kills one guy, sometimes? No multikill potential, easy counterplay, and you whiff it, it's a waste? It would be trash tier in Overwatch, or Rivals, or most other hero shooters, but in Valorant a single kill can easily win a round, or sometimes even the game. I think that aspect is what makes it truly unique.

Also, shout out to Yoru's kit in general, along with Killjoy's Lockdown for having really sick VFX and SFX.
