Coros - Apex 2 vs Garmin - Instinct 3 Tactical

The Instinct 3 Tactical is the clear pick on raw spec strength, leading by 9.6 points on the Mars Score. The margin is wide enough that the underdog only makes sense if its individual strengths line up with what you specifically need.

The Apex 2 doesn't pull ahead on any single popular-comparison spec — its strengths sit in the spec table groups rather than the headline advantages.

Pick the Instinct 3 Tactical if you care most about smartwatch mode and gps mode. Its strongest claims are smartwatch mode, gps mode, solar charging.

Both ship with comparable multi-band gps, ecg, so those specs don't separate the two — focus on the differences below.

Bottom line: the Instinct 3 Tactical is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
