Best wearable device to track steps, heart rate and sleep under $250, with the following restrictions.

Hi all,

This is a question I could have perhaps googled the answer for, but I wanted personalized answers and not lists curated by one person, so I decided to post. Thank you for your time.

I am looking for a wearable device (ring/band/watch) under $250 to accurately track my daily steps, heart rate and sleep. I would prefer the device to be of the wear-it-and-forget kind of device, so I'm leaning more towards a ring or a band (basically not something that sends emails and alerts on my wrist). I would prefer not to be on a subscription model, but if you guys very strongly recommend, I could shell out up to $200 yearly for the subscription. I am only looking to use it to track my steps, heart rate and sleep, so I don't want anything too fancy. Design is of no consequence to me, unless it is outright ugly. The main purspose is to get data that I can then use to lower my chronic inflammation.

I'm mostly looking at the FitBit Air, but I'm open to pretty much anything.
