@Reply’s question is probably most pertinent. “What do you need in a smartwatch?”
@Roderick_Femm mentions cost ($200 watch), reliability, and a few really basic features. In terms of reliability, yeah, Apple watches are in a rank of their own, but not really an option for us Android users.
If you go with others, I used to avoid Samsung like the plague, their proprietary Tizen system was a terror, but with WearOS it’s an also run. If you’re buying a cellular enabled one (not that I’m recommending it) it would be worthwhile going through your mobile carrier, and probably getting better service, though that’s not saying much.
For the needs mentioned though, I don’t think it’s a big deal, though the fall detection services on modern no-phone required cellular smartwatches can be a boon for active but more elderly individuals. Google Pixel makes solid watches, no bloatware that plagues Samsung devices, so it’s a solid choice. OnePlus is (IMHO) roughly equivalent to Samsung, decent, but with more bloatware. One not in the list, that I use, but not sure I’d advise is the Ticwatch series. They are function packed, but cheap in price (I personally like the dual layered screen, a “generic” digital watch with time date steps and then tap for active full smartwatch mode. Long battery life that way. But they use a bunch of less-than-ideal secondary apps, they’re bad about updates to the OS, and … finicky? You’ll probably need to be comfortable with forcibly rebooting the thing at least once every six months. So good value for money, but more work than a lot of people want to do.
Still at $140 (not on sale even) this model isn’t too bad a choice for what is, sadly, an ever more use-it-until-it-dies device. People talk about smartphones, computers, and browsers getting obsoleted, it’s far worse for smartwatches IMHO.
Oh, one last niche thing I like about the Ticwatches, they have both speakers and microphones, so in the case you want to take a call without a BT headset, or getting your phone out of the pocket, you have that Dick Tracy moment available to you. On previous models, I’ve even (poorly) streamed video on it, though only as a “see what it can do!” moment.
BUT - again, if you want reliability, I’d probably pick the Samsung (again) or Pixel as the best Android choice, or something with less adaptability and more reliability like Garmin.
