Garmin for sure.
I’ve had a Fitbit, Samsung Smart, and Garmin. Fitbit and Samsung were almost a daily charge where my Garmin Solar lasts about a week. Both Fitbit and Samsung died on me roughly after a year and a half, Garmin has shown no issues.
There’s only one smart watch that matters! This was the boyo!
All my phone numbers, my entire school lesson schedule, a calculator - everything 10 year old me ever needed!

While there are a lot of comments saying Garmin, I haven’t seen people mention the privacy aspect

Garmin apps are much better for privacy. If I’m going to be wearing a biometric tracker 24/7, I don’t want that data being sold to advertisers. That’s more important to me than most other features
Still miss my pebble…
Rocked a Garmin a few years, now I’m trying galaxy watch 5 pro. Miss the week long battery but 2+ days is “ok”, a lot less annoying then I first thought it would be.
Exelent integration with my phone is a big plus. (For instance the Garmin never let me respond to alarms from the Samsung clock app :/ )
