display quality
Product 1: Garmin Forerunner 255S
3.9

The MIP display is practical and readable rather than flashy, with reviewers trading away AMOLED vibrancy for battery life and outdoor usability.

durability
Product 1: Garmin Forerunner 255S
4.4

Durability looks good in longer-term use, with reviewers reporting little wear, though the bezel and glass can still be scratch concerns.

Product 2: Apple Watch SE 3
3.9

Durability is improved through tougher Ion-X glass and water resistance, but some reviewers still point to weaker scratch or dust protection than pricier models.

ECG functionality
Product 1: Garmin Forerunner 255S
No score yet
Product 2: Apple Watch SE 3
