Polar Vantage V3 vs Whoop 5.0
Our pick: Whoop 5.0 takes it — 83 vs 78.
Both are strong — the call comes down to what you prioritise:
- Polar Vantage V3 — Serious triathletes and multisport/endurance athletes who want deep training and recovery data plus long battery life.
- Whoop 5.0 — You train by readiness and want the deepest recovery and strain analytics in a screenless band — now with medical-grade ECG and blood-pressure metrics.
Polar Vantage V3
A hardware powerhouse for serious endurance and multisport athletes: class-leading battery, dual-frequency GPS and a deep sensor suite (ECG, SpO2, skin temperature). The training and recovery analytics are outstanding, but the smartwatch side stays barebones and the price only makes sense on discount.
Whoop 5.0
A 14-day battery, a 7% smaller band, on-demand ECG and daily blood-pressure insights — the biggest Whoop leap yet. It's still screenless, still subscription-only, and heart-rate accuracy still isn't quite elite.
