Twitch (well, broadly the Western indie scene) is where most of the advancements in Live2D and model tech has come from.
Because Twitch is a much more open platform there's a greater deal of interactivity between streamer and audience, which means there are things Twitch streamers can do that YT streamers can't, and that extends to vtubers.
VTS and Warudo are much more stable and feature-rich than their corpo counterparts.
Indies experiment with what a vtuber can even look like, not just from the perspective of aesthetic but the poses and angles of their L2D models.
Today alone saw three different debuts showcasing things that have only become possible because the Twitch/EN indie scene has the freedom to push these boundaries.
Zentreya's fluid and precise 3D tracking. This is actually a proprietary 3D program she's having developed which will eventually go public.

The stranglehold Japanese corpos have over the industry there means that everyone is just following in their rigid, bureaucratic steps and that leads to stagnation. The JP vtubers who are trying something different are few and far between, and the lack of traction they receive for their efforts disincentivizes other people to try.
