It depends on what you need it for. Most people would be fine with a Venu3 honestly.
Venu3 is sufficient for that and doesnt look so sporty so you can wear it on regular days too
I have a 45mm Venu 3 that I wear year round. I use it to track my outdoor cycling and that ends up being around 10 hours a week of stressful activity tracking. I love it and wouldn't trade it for anything,.
I was going to buy the Venu 4 but the Venu 3s was AUD$350 cheaper with the same heart rate sensor as the 4. All features on the 3s are more than enough for me (someone looking to simply track my fitness & wellness journey) I jumped ship from an Apple Watch series 11 which I trialed for two weeks - no matter how many times I read “just charge it when you shower” I still had battery anxiety and hated that I had to take in to consideration my battery levels whenever we went out anywhere The venu 3s does everything the Apple Watch could without feeling like I’ve strapped a mini phone clone to my wrist. In fact I’ve decided to dumb it down further, I’ve tuned off notifications and sounds and keep Bluetooth off until I sync the watch in the evenings. I am purely using the Garmin to focus on fitness and not as a device to be connected

It fits directly into your usecase. It's designed for athletes who care about health, provides the data you need to optimize muscle growth and recovery, and you only have to charge it once a week. Pair it with a proper BP cuff, and you have a complete, reliable health monitoring system.
I migrated from FitBit Versa several years back when I got the BSOD a couple months after the warranty expired. It was a well-reported issue on their forum, but the best FitBit could do is offer 25% off from their website. Switched to Garmin and my Vivo4 lasted 2 years past warranty and I only upgraded to Venu3 because the battery charges were not lasting as long.
