LoremCDMX is the best among Russian-speaking ones. To lesser extent - babyshark4.
Also I like when Bencb or Goosecore are streaming, they usually do it on raiseYourEdge or pokercodeofficial channels respectively. When a bunch of German pros were gathering together and streamed on nolimit_gg it was legendary. Maybe they still do from time to time (although less likely with corona and different locations), I haven't been updated about them for quite some time.
By the way just find out that Bencb is streaming right now FYI
