Each to their own preferences. Some of these sources disagree with each other, and that’s a good thing. The worst place to belong, is within an echo chamber. Always think for yourself, and try to understand where others are coming from (why they came to the conclusions they did).
As for Louis… honestly, I prefer his tempo. It feels more genuine, less like he’s putting on a show for the camera. In the tech world, take Craft Computing, LTT, or Jays2Cents as examples. All have gone on record to admitting to putting on a show, changing how they talk, etc, while on camera. If Louis is putting on a show, I gotta admit, I’m impressed. Hats off to the guy.
