Need to pick a smartwatch

[AntiqueStructure]

So I currently have a very scratched, and kinda broken (bought it used cheaply), pebble time. I was looking into buying a good used REAL smartwatch from the new gen that have decreased in price. I was looking at the Moto 360 sport, and the Gear S2. The sport is ~140$ on amazon, and the Gear s2 is ~160$. I want to use it for running casually 3-5 times a week (about 10-15 miles a week), and use hr tracking. I know that the sport has GPS which is huge, because I will not be running with my phone, however not having GPS is not a complete dealbreaker. If the regular smartwatch use is much worse on the Moto, than I will happily take the Gear s2 (I have a note 4), but if the difference is very close, than I would probably go with the Moto because of GPS. If anyone has any comments on the watches, and their normal functionality that would be great. To me, the screens are both good, the rotating bezel is kinda cool but not necessary, and the not replaceable straps are annoying but okay. If you could give me you thoughts and opinions that would be great

Thanks

Personally I use a first gen Moto 360 and it's held up just fine. Android Wear isn't very demanding at all so I don't even notice performance issues. I think they're only like $100 now which is pretty crazy. I see no reason to go with the second gen at this point.
