best smart ring that actually has accurate sleep and stress tracking?

I’m mainly interested in a smart ring for sleep quality and stress tracking since my schedule has been pretty inconsistent lately and I want something simple I can wear 24/7. I keep seeing mixed opinions on whether the data is actually accurate or just rough estimates that look nice in an app.

For people who’ve used smart rings long term, which one actually felt the most trustworthy for sleep trends and stress or recovery tracking, and was there one that stood out in terms of app experience not feeling confusing or cluttered? Thanks
