I generally watch all of them except the All Girls and Two Guys - sometimes I learn something, or see something interesting, either featured or in the background.
There's a couple others I've checked out, but couldn't get "into".
Some of them can be pretty funny at times - just being some guys clowning around - though sometimes the "technical fiction" is silly and/or irritating.
I do keep in mind that's it's TV/streaming, and biased towards someone's idea of entertainment vs tech or reality.
A lot of the shops do seem to get stuck in a rut, and some spend too much time patting themselves on the back.
Recent episode of Roadkill with the boat-car and quickie rental-car Nitrous was really funny.
