I feel like my Oura is pretty accurate. The fact it's a ring makes it very comfortable for sleeping, no issues at all. FWIW, my sleep doctor says Oura rings are not accurate at all, but anecdotally I don't agree with him. I do find the Oura is terrible at tracking activity like exercising, it's just wildly wrong. But for sleep it seems very accurate.
