I upgraded mt watch 7 to the new Watch 8 Classic. I do love it, it's a bit bigger but perfect for the size of my wrist. The only thing I have noticed is it doesn't seem to hold battery life like my 7 did. I would still recommend it.
I've used Samsung phones and watches (exclusively) for the past 15 years. The quality and functionality of this watch is great! I went back to the classic model (rotating bezel) and really enjoy the look. I also use my watch to listen to music on the gym floor without having to bring my phone. LTE is enabled for talkability without my phone as well.
This watch works as well as it looks! Had the GWC6 but appreciate the update. Battery isn't particularly better but I charge it nightly, per my past habit.
