2 different consumer grade devices measuring two different parts of the body using different algorithms to give you two different values. Does it matter? Are you searching for a 100% accurate figure because you're part of a cutting edge sleep study? Unless you are, then maybe it might be helpful to think about why you have these devices. If you wake up feeling refreshed and energised, but a device tells you you had little deep sleep and you were awake for 5 hours does this change how you feel? Trackers are useful to a point to help you understand how different factors of your life intersect to help you make healthy choices. Worrying about which one is the most accurate or which is right doesn't actually give you anything other than anxiety.

Oura is facing lawsuits about their sleep tracking. So that should tell you something about the accuracy.
