While I love the Oura Ring for everyday use, nothing beats the Apple Watch Ultra for me when out on hiking/running trails and in the weight room. The big display is perfect for quickly glancing at pace, cadence, and heart rate data while running, and I appreciate the first-class integration with the rest of the Apple ecosystem. While the ~2-day battery life is a big improvement from earlier Apple Watch models, I do wish we could triple or quadruple that in time.
