I found the glass durability tanked between 3 > 5. My 3 was spotless, 4 wasn't as good, 5 was bad.I've gotten into a groove where I upgrade to the newest AW whenever it incorporates new sensors. Rectangular or rounded doesn't really make a hell of a difference to me. So I'm on the AW6 right now. Regarding it, anyone else have glass scratch problem with AW6 or AW7? I always buy the cheapest AW, but never had a scratch issue with previous AWs, but my 6 has gotten pretty noticeable ones since I bought it - and god knows, I haven't been that active during covid :-(
I went with a SS/sapphire for my 7. Joke's on me.
