I like the Samsung round display and rotating bezel as well (I wasn't as fond of the Gear 2 and Galaxy Gear relying so much on gestures) and am surprised Apple still makes a square watch in this day and age.
So far the Galaxy watch series is the only new product from Samsung that still gains my interest (I haven't been fond of their phones since One UI replaced TouchWiz Nature UX and became as large as tablets or remote controls)
I'm still using the first Galaxy Watch (2018) that is fully-functional even when paired to my 7-year-old Galaxy S5. I just love how it looks, how it lacks a leather band (I'm vegan), and the rotating bezel isn't as resistive as the one on my Gear S3. I didn't like the way the Galaxy Watch 2 looked, though. I also wasn't as fond of later Gear Fit models since the first Fit just had a nicer look to it (the later Fits seem so cheap and plasticy looking)
Haven't seen a display for the Galaxy Watch 3 though, but it seems to be a good time to look.
