Our quick verdict
The Amazfit T-Rex 3 Pro, a smartwatch with a 1.5-inch OLED screen, lasts longer between charges (25 days vs 14 days) and has built-in GPS for runs without your phone, while the WHOOP Life, a screenless tracker you read in the WHOOP app, takes ECG heart-rhythm readings and gives daily recovery and strain scores, though it needs a WHOOP membership.
