Compare Coros Pace 4 vs Suunto Race 2

Heart-rate accuracy was usually good for steady running, but reviewers repeatedly saw weaker results in intervals, cycling, gym work, or cadence-lock situations.

Heart-rate accuracy was the most debated upgrade: many reviewers called it a major improvement or accurate enough for training, while several still found unreliable readings in hard efforts or certain workouts.

GPS accuracy drew the strongest agreement: most reviewers found tracks and distances excellent, with only occasional drift or margin-of-error complaints.

GPS accuracy was generally strong, especially for land workouts, but several reviewers saw small errors, worse open-water results, or a slight step back from past Suunto performance.

Sleep timing was often acceptable, but sleep-stage accuracy and the watch’s judgment of poor sleep were questioned by several reviewers.

Sleep tracking drew split feedback, with some reviewers praising sleep timing or nap detection while others reported missed awakenings, hit-or-miss nights, or overly ambitious deep-sleep estimates.
