GPS and navigation

Polar Vantage V3 improves significantly with dual-frequency GPS and built-in maps. For following a planned route, it is enough for many athletes. Garmin Fenix 8 remains more comfortable for improvising, zooming, changing routes, and managing multiple outdoor sports.

Battery and charging

Health, recovery, and price

Polar is very readable for recovery, cardio load, and sleep. Garmin offers more metrics and connected features, but its price is much higher. At equal budget, Polar Vantage V3 leaves more room for a heart-rate strap or shoes.

Verdict: Garmin for outdoors, Polar for progress

Buy Garmin Fenix 8 if you want the best premium outdoor watch. Buy Polar Vantage V3 if your priority is training, recovery, and a more reasonable price.
