Withings Body Comp

What works

8-electrode segmental BIA provides left/right limb separation — identifies muscle imbalances between dominant and non-dominant sides that 4-electrode foot-only scales cannot detect
Visceral fat grade and vascular age metrics are clinically-referenced — cardiometabolic health indicators not available on Garmin Index S2
Withings Health Mate stores 7 years of measurements with trend analysis — the longest longitudinal health data set in consumer smart scales

What doesn't

$199 vs $149 for Garmin Index S2 — $50 premium for the handle electrode and segmental measurement capability
WiFi setup requires 2.4GHz network — 5GHz-only network configurations require router settings adjustment

Garmin Index S2

What works

Native Garmin Connect sync pushes scale data directly into Garmin wearable training load calculations — body weight affects VO2max estimates and training status in real time
16 user profiles per scale is the highest capacity in the category — appropriate for large households or small training facilities
$149 vs $199 — $50 less for buyers who use Garmin ecosystem and don't need segmental body composition

What doesn't

4-electrode foot-only BIA cannot provide segmental left/right limb composition — less detail than Withings Body Comp for asymmetry tracking
9-month battery life vs 18 months on Withings — requires more frequent battery replacement for a 4-AA unit

Bottom line

Our pick: Withings Body Comp.
