The Amazfit Balance 2, a smartwatch with a 1.5-inch OLED screen, lasts longer between charges (21 days vs 14 days) and has built-in GPS for runs without your phone, while the WHOOP Peak 5.0 Sensor, a screenless tracker you read in the WHOOP app, gives daily recovery and strain scores and is lighter to wear all day, though it needs a WHOOP membership.
