What I love about my Garmin is it does all it does without a subscription. I’ve looked at oura, whoop, and withings and they all need a subscription for full functionality. It seems Garmin bakes that cost into the device price, so you pay more up front but also get what you pay for.
My Venu 2 is awesome. Sleep, stress, body battery, vO2max, and almost any activity I do including hike, bike, snowshoe, snowboard, paddle board, disc golf. The battery lasts 5-10 days depending on how much GPS I use.
It has a few smart features but the above is more important to me.
