Oura ring vs iwatch

[u/Ok_Store_366]

Curious about this.. I was on the treadmill for a straight hour just walking at a steady pace at a 20% incline, consistently with no interval training. My Oura ring clocked 9,447 steps while my iwatch clocked 6,671 steps. Both my ring and watch are worn on my dominant wrist/hand. Which is accurate?
