MKBHD simply because I have absolutely no idea what the point in the channel is.
Obstensively it's a tech review channel, but really it seems to be a look at my cinematography and all this b-roll footage channel. Also iPhones, which is always boring because let's face it the last time Apple did anything close to innovative with the iPhone was the the 5C.
I mean you nailed it. It's entertainment - validation for people who want to buy the shiny new Apple thing. "Look how cool it looks in these artsy shots", forgetting it's a carbon copy of last year's model.
I use MKBHD as a source of surface information to find quick info about certain products. Of course the info he gives out is a little biased but the videos are short and entertaining. Still end up doing my own research before purchasing though.
