Well, with how power hungry my AW8 is, it’s more like 22.5/7.

Apple Watch is the most precise in terms of metrics, and beats even Garmin Fenix in this regard.

Other metrics are also more precise, such as sleep tracking, which in combination with other metrics, provide insight in your restitution.

The only drawbacks for Apple Watch are the low battery life and, subjectively, that it looks ugly.

I chose the 8 a week ago, due to the 9 simply not having enough new in comparison the 8. Might as well save the money and spend them on peripherals. Next year, we’ll see what the X/10 has to offer.
