> Maybe less powerful but battery life is the most important feature for me.
I've been using Garmin watches for years, wife always had Apple Watches. This year she got envious enough of the battery life that she also switched to Garmin now. Her watches sometimes barely lasted a day, requiring daily charges. Meanwhile, you get a week of battery easily with most Garmins.
From Apple:
"Apple Watch Series 12 continues to offer up to 24 hours of everyday battery life and now offers up to 10 hours of battery life during an outdoor workout — 25 percent more than the previous model.
Apple Watch Series 12 also offers faster charging: Just 15 minutes now gets up to 12 hours of additional battery life — 50 percent more than the previous model — so users can quickly recharge while getting ready for the day or before bed."
