I would recommend it
I don't know how it is on the Ultra but I had a Galaxy watch 6 and the damn thing couldn't track my heartrate during a workout. Most of the watch was nice but the fact it couldn't do something a $100 Fitbit could do was a deal breaker
I've been a huge Fitbit fan up until very recently. I was nervous about the Google takeover, but everything seemed to be going fine while my products were still under warranty. The first update after my Sense 2 was out of it's 2 year factory warranty, the battery life started tanking and it started shutting itself off when it was tracking workouts(even when fully charged). I tried all of the reset they recommended on their community page and was recommended the same unhelpful steps from customer support(from my extensive googling of this issue, this happenes a lot nowadays). After a few weeks of me stubbornly clinging on through the frustration, it just stopped turning on at all, just kept leaving me in a blinking red 'x' loop until I gave up and switched over to my partner's old Galaxy watch 6. I'm still mourning my Sense 2, but have been very happy with the Galaxy capabilities and tracking. Fitbit used to be a great product, but Google seems to be bricking them as soon as the two years factory warranty is up. TLDR: Fitbit is great while they work, but brick the first update after warranty is up. Samsung Galaxy watch ftw.
Thank you, I'm lowkey still in mourning, but at least having a good watch to transition into has really eased the sting! 😂 It's about the same thickness. The face is a little larger, which I was kind of nervous about because I have super tiny wrists, but it's still nice and comfy on my bird wrists and doesn't snag all crazy on sleeves(another concern before I tried it 😅). I saw you did have concerns about battery life; I charge it daily when I'm in the shower, so it never really gets low(it's usually at 70ish% when I go to charge it), but it was pretty fast to fully charge from dead when I switched over.
I personally used xiaomi band 6 and samsung watch 6 and i have had bad experience with the band 6 because i wanted to use it for tracking sleep and one day i was sleeping and woke up to see the display being poped out. Issue with Samsung watchs are they are too big to sleep comfortably with rest its better and has more sensors and i also prefer the samsung health app. For a budget option i personally havent used it but i heard a bunch about it and it's samsung fit 3.
You can buy samsung watch 6 i have it and i track my runs sleep with it and also gps is also there
Most Galaxy watches need to be charged daily and the sleep monitoring system is annoying. The health app needs to stay opened to monitor sleeping patterns for the night. On the plus side, the watch now does blood pressure (and it's approved by the FDA). Fitbit was great until they started the monthly fees for their ecosystem. I really wasn't upset when I lost mine doing yardwork and I replaced it with a Galaxy 6. I am 71 and I love mine. I wasn't thrilled about the need to change it so often tho. It's over 2 years old, and now, sadly, it doesn't last a minute over 24 hours. I get alarmed when it turns itself off (and I'm just relieved when I can turn it back on after half an hour on the charger). I recently started keeping an extra charger in my car just in case. Yesterday, I found a place that will replace my battery. It seems like a lot of money, nearly half the original cost, but buying the 8 would cost a lot more now. I don't think that the slight improvement between the 6 and 8 technology is worth the upgrade yet. I plan to wait until they have batteries that last longer than a day. (I still have my ancient Galaxy 3 because I love the rotating bezel).
