It's a welcome break from the exaggerated emotions, fast breaks/cuts, and general dopamine triggers that are littered in your average youtube video. It's like watching Bob Ross. I love Asianometery!
He's sometimes a bit too (economically) left-wing for me, but I generally sticks to well-researched facts, so it has never been an issue that would impair my enjoyment.
But like you said, he provides a lot of well-researched facts that allow a viewer to form their own opinion.
(That's probably a better term than the rather imprecise left/right shorthand.)
He seems to have a soft spot for 'industrial policy'.
Eg when he discussed the rise of Chinese photovoltaic, and the relative decline of German efforts.
