It’s a pretty lame idea

It’s pretty good. If all you really care about is activity tracking and don’t need the other smart features, get a Garmin

Yes

I have an SE2 (which is the SE is the market now). There isn’t anything about newer models that I think I’m missing side from always on display (which I’m not even sure I’d want if it was an option). It works great and is still lightning quick

tbh if you have an iPhone then I wouldn’t bother with anything other than an Apple Watch. It’s a good watch, but the main issue is that other watches don’t play well with iOS. I had a Garmin paired with an iPhone m and the notifications were a bit of a mess and they can’t be customized

More choices if you have Android (though obviously Apple Watch doesn’t work)

I came from Garmin and the Apple Watch is great. The workout tracking is excellent and unless you’re a serious athlete or training for a triathlon, it gives you more than enough data with the built in workout app, and you can also use third party apps like Strava or WorkOutDoors (or use HealthFit to sync)

I never really used the Body Battery or the stress monitoring, both of which I found somewhat gimmicky and I was sceptical of the science behind them (especially the body battery).

And of course the non-fitness smart watch features are no comparison, Apple Watch by a mile

Battery life took some getting used to but you can get into a routine to charge it every day and it’s fine. In some ways better than having to keep track of the battery to decide when to charge it

It’s a nice user experience and the ability to easily use Airpods is nice it you use it. AirPlay, too, although some smart TVs now have this. Apple Arcade is relatively ok if you would use it (though it is a subscription)

To be honest, if you have a smart tv that does what you need, you’re not going to get a lot more out of the Apple TV to justify the cost, as long as your TV supports the services you use
