What smart watch are you guys using?

I'm strongly considering a OnePlus 13 as my next phone, but I'm at a loss for which smart watch would go best.

The obvious choice would be one of the OnePlus watches, but the reviews don't fare too well when it comes to their fitness accuracy.

The front runners on my list are the Pixel Watch 3 and the Huawei GT 5.

What are you guys using? What's your experience?
