Normally his tech reviews / insight are a mess but he was pretty accurate in this video, although more long winded and complicated then it need be.
Basically...
From smartest to dumbest...
1. Apple Watch
2. Android Watches
3. Fitness watches like Garmin / Fitbit
4. Regular watches
He also shows the battery life is inverse of the above, which is a valid point. He is clear the build quality and ecosystem is by far the best on the Apple Watch but points out the running and fitness tracking on the Garmin is unparalleled and with good battery life.
He advocates using the one that fits you best. Just want to know someone is calling / texting and love to run? Get the Garmin because then you get world class tracking and 2 week battery life. Want a true modern computer on your wrist that is like a fine piece of jewelry? Get an Apple Watch. Don't have an iPhone but want a closer to Apple Watch experience? Get an Android Wear. Don't want to deal with something on your wrist but the time? Get a regular watch with 2+ year battery life.
Pretty straight forward but not wrong.
