I have a Gear S2 Classic.
Even not being able to use it for payments where I live, it was nice for music controls, calendar reminders, triaging messages (read: not bothering to reply if I swipe them away and don't get my phone out), rejecting calls, timers, basic activity tracking, and of course telling the time. I did use it for regular days and found it worth charging every night, though eventually the strap broke (again, after several years) and I just didn't bother replacing it. More modern smartwatches have a few more features that are nice.
I will say that having to charge it every night (or two) was a bit much and probably why out of inertia I didn't bother going back to it in the end. I wore it often for a good five years though. Now I use a Polar sports smartwatch that lasts about a week. Not having to charge it so often is a big plus. Still no niceties like payments, but it's a professional sports device that gives me lots of pretty graphs to tell me how unfit I am and badly I sleep (best in the business ones).
All throughout though, I have worn analogue and digital watches, especially on trips because fuck charging more than a phone on them. And nothing beats a nice analogue watch with a suit. Don't be the arse who wears a smartwatch to a wedding or the like; have some more respect for yourself. Could be worse though, you could have been a Glasshole.
