This is a training focussed comparison from another athlete. He deep dives sensor connectivity, third party training platform compatibility, usefulness of workout screens during actual workouts etc. Sleep and recovery tracking etc.
This thankfully isnt another "the watchfaces are super pretty!" type review.
It's a reminder for me at least cut Garmin a little slack. I haven't realised how far ahead of Apple they are in certain areas such as customised workouts, being able to see which sensors are connected and obviously mapping etc, and how much of a backwards step it would be by moving over to the Ultra.
There are many features about this watch I use on a daily basis that I really do take for granted 
He got an excellent marathon prediction for his London marathon. In your video, his watch was predicting 3:29:37.
in this video, he does it in 3:31!!
