Summary of user reviews:

Positive points:

• 3 out of 4 reviews speak of very good overall satisfaction. The watch clearly appeals to a majority of users.
• 2 out of 4 users strongly highlight the autonomy, considered excellent and suitable for long outdoor outings.
• 2 out of 4 reviews emphasize the robustness and “terrain” aspect of the watch. It inspires confidence for the mountains, outdoor activities and areas without a network.
• 2 out of 4 users particularly appreciate the integrated GPS and free offline maps, considered a real advantage in the field.
• 1 user evokes a real aesthetic crush thanks to the bracelet, which completely changes the visual appearance of the watch.

Negative points:

• 1 in 4 users strongly criticize sports and health monitoring compared to Garmin:
  • HRV measured only once per day
  • Wrist cardio deemed inaccurate during sport
  • Mandatory return to a cardio belt
• 1 review out of 4 finds the ergonomics perfect:
  • Menus considered not very fluid
  • Too much manipulation
  • Limited customization of training screens
• 1 user believes that the integrated flashlight clearly lacks power and remains a gadget in practice.
• 1 user ultimately left Suunto to return to Garmin because of the compromises considered too significant.

Shared/mixed points:

• The level of onboard technology divides slightly:
  • A user loves the amount of information available quickly.
  • Another finds the interface and customization options too limited.
• Solar power is appreciated for autonomy, but is not necessarily enough to convince very demanding users in terms of sports metrics.

Advice :

If your priority is the outdoors, autonomy, long mountain outings or activities far from the network, this Suunto seems really very solid. Feedback on battery, robustness and GPS comes up several times.

On the other hand, for athletes who are very demanding in terms of health data, recovery or advanced cardio monitoring, Garmin seems even more convincing in several aspects. So it clearly depends on your actual use.
