What's the feature that makes it most compelling for you? Screen size? I'll grant that going from 3 to 4 was a pretty big screen bump -- maybe this will be similar, in which case it could pique my attention.

The always-on display is appealing, I've been looking forward to getting that ever since the Series 5 was released. But it won't be enough by itself to get me to put down the cash.

I was hoping for thinner, and sorta hoping to see a design update along the lines of the iPhone 12/13.

It sounds like you two may place different value on some aspect of these devices

Actually, I think the reason they're still selling the S3 is because it is quite different visually. If you don't mind having a watch that has a much smaller screen (which affects usability and isn't as 'prestigious' among Those Who Care) then you can get an Apple Watch for a price point that rivals Fitbit etc.

Note: I am not one of Those Who Care — I still rock my Pebble Time Steel!

Was the Series 3 the one where you have to perform pagan rituals in order to update the OS?

It is. However the LTE models (and I think the ones they’re selling now) have more storage space, and iOS 8 also allows updating with less free space as well. Still, the S3 is completely outdated now

Supposedly watchOS 8 changes the upgrade mechanism such that it does not require pagan rituals. Although you need to get a pagan ritual to get it initially onto a Series 3.

No, this model specifically requires two rain dances and a dream catcher. Close though!
