I’ve had the Apple Watch series 5, and this one is not a huge improvement but it’s definitely better than the series 5, it’s super snappy, has all the health features I want, and the notifications work perfectly. Definitely recommend for a busy person or someone wanting a top Of the line fitness monitor. I have had it for about a month now, and I don’t think there’s con’s to it at all. The Nike version is great compared to the standard one because of the holes in the strap. I found mine getting a bit sweaty with my normal apple series 5 Watch, but with the Nike straps it works perfectly to stop me sweating etc.
