RingConn Gen 2 Air vs Google Fitbit Air

I currently have a RingConn Gen 2 Air, but I have Google everything and all I really care about is calories burned and workout tracking, and sleep tracking and IDK which is more accurate at tracking calories burned and I know RingConn doesn't track distance or mileage, but to my knowledge the Fitbit Air does and I am wondering if I should sell my RingConn and buy a Google Fitbit Air instead.

What are your thoughts?
