Polar Vantage V3 vs Whoop 4.0
Sqwod verdict
Our pick: Whoop 4.0 takes it — 85 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 4.0 — You coach performance and program by daily readiness and strain.
Polar Vantage V3
78Score · Medium
from €399
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.
Our pick
Whoop 4.0
85Score · High
from €30
The coach's strain-and-recovery band — screenless, always-on, built for athletes who train by readiness. The subscription model is the commitment.
