On comparing the health monitoring features, we found the Garmin offers much more in this section. Both the watches have common health monitoring features like heart rate monitoring, sleep tracking, SpO2, stress & recovery.

However, Garmin Fenix 6 Pro has more to offer, Garmin brings more attention to heart rate monitoring with features like abnormal heart rate alerts.

Something similar is done by Suunto 9 Peak, both the watch use VO2 max levels to interpret it.

For swimmers, both watches provide metrics like pace, stroke efficiency, time, length, and lap. In the case of running both watches provide basic metrics, but need additional compatible accessories for some more detailed and specific information. Support for other sports is also available in detail to monitor and improve your performance.


On comparing both the watches, we found that Garmin Fenix 6 Pro offers a little extra feature than the Suunto 9 Peak. However, Suunto has everything necessary, so choosing Suunto will also be enough for a professional-level athlete.

Garmin has more features and they are advanced but Suunto also covers everything and present in a simple manner that is easy to understand.

In brief, the best smartwatch for you depends on your requirements. However, if you are someone who doesn’t have any specific requirements and just wants the best device, we would advise you to go for Garmin Fenix 6 Pro. The Watch has more features to offer and more detailed metrics.
