Whoop 5.0
Battery runs 14+ days at 26.5 g, with no screen or GPS. You can't buy the band alone, since the hardware comes bundled with a membership.
6.2/10
This score is my reading of published evidence, since I haven't worn the band, and it's conservative because I found no peer-reviewed test of the 5.0. The app is well liked, but the membership never ends and wrist heart rate is disputed.
