/vt/ - Virtual Youtubers

Let's specifically discuss face tracking, and whether or not if it makes that big a difference to you. For me, it does matter but not as much if the Vtuber has a good personality. For example: Projekt Melody has one of the worst mouth tracking I've seen across all Vtubers, but she's funny so I can forgive it. But Snuffy has one of the best, so much so that sometimes I just watch the way her eyes and lips move and pay as much attention to that as whatever the hell she's saying at the time.

Which Vtubers have you come across that have particularly exceptional or atrocious facial tracking?
