What is the best sleep tracker?

I honestly wasn’t planning to upgrade anything related to my health tracking anytime soon, but my current sleep tracker just started giving me trouble out of nowhere.
The sleep data feels inconsistent, syncing fails randomly, and it’s gotten uncomfortable to wear throughout the night.
So now I’m stuck because I actually need a replacement sooner than I expected.

While checking different options online, I ended up shortlisting two sleep trackers that seem to be getting a lot of attention.
But still not sure if they’re truly worth it or just getting hyped:

Oura Ring

Whoop Sleep Tracker

https://www.amazon.com/WHOOP-Life-12-Month-Membership-Pressure/dp/B0DY2PB7RB?th=1

My requirements are pretty straightforward:

  • Accurate and reliable sleep tracking
  • Comfortable enough to wear all night
  • Durable build so I don’t have to replace it anytime soon

If anyone here has tried these or has real user experience, please share your thoughts.
I’d really appreciate some guidance before I make a final decision.

Thanks in advance!
