I'm probably the odd one out in that I usually watch smaller artist VTubers. I like watching the creative process and the close knit communities that I become a part of when I'm watching.
All of these VTubers can be found by searching their name on Twitch:
Pastelmonstaa
AwokenArtist
Viveltya
GrimPaleta
Sylvie_Inori
Yoijoe
Mielitta
Belindraw
Mamorandom
Sylvie is the odd gamer out, the rest are primarily art streams with a few game streams scattered in between. Yoijoe is also primarily a gamer, but has started learning to draw as a part of this artist community, so has a similar mix of art and games streams.
I watch quite a few, but I gotta shout out an indie I am a big fan of: Lily Hopkins!
She streams a variety of content, occasionally does ASMR, has a charming little sister shtick, and is just a generally nice and funny human being. Definitely check her out!
My friend Embii the Wizzboi has been streaming for just under a year, but has a higher quality stream than most. He also has a unique art style comparatively to a lot of newtubers.

Otherwise I enjoy watching his friends streams SoogePooge the Marshmallow or Mimi_Fox_pxl.
