Should I take it from this response that you have no actual criteria for a solid stream and that it's just your confirmation bias at work here?
Here's how I see it: (1) I give you recommendations, and then you will likely dismiss them due to some unclear, vacuous, and yet provided criteria that I am not yet privy to. Or (2) I don't give you recommendations, and then you take this as some sign of your argumentative victory.
So I apologize if I am cautious about providing recommendations, but you should not mistake that for a lack of possible recommendations. Similar past efforts, IME, are rarely productive fronts for discussion.
It's possible to build up the good qualities of D&D for streaming without claiming that (a) it's uniquely suited and/or (b) other non-D&D games are somehow less suited for streaming.
However, you are implying that D&D (5e) is uniquely exceptional in its ability deliver good streaming content over against other non-D&D games, but have neither established any criteria for that or evidenced any actual argument against other games. It's just a baseless drive-by blanket tribalistic statement that's trying to promote D&D as being better than other non-D&D games without anything to back it up.
I have watched a number of good streams for Fate, Cortex Prime, Numenera, Blades in the Dark, Savage Worlds, Fantasy AGE, etc. There are also, of course, good streams for D&D-adjacent systems, such as Stars Without Number, Index Card RPG, and Pathfinder (1 & 2). Not every one will be up to the snuff of Critical Role, but that's hardly a fair comparison given the combination of Critical Role's talent, production value, and market privilege that D&D enjoys.
