Personally I find the "random shit on camera" is just fine, as long as the delivery is sufficiently appropriate. But my use case is usually to help me unwind and get to sleep so if the content is too interesting it's counter-productive.

I think the true effect you're probably referring to by the 'unintentional' ASMR is hard to achieve so I guess I don't hold most of the Youtube stuff to that standard as long as I get what I want out of it. I guess this is a long-winded way of saying YMMV.

That said if you or anyone wants to make some suggestions of high-quality ASMR videos I'd be interested.
