Scorata scores summarize analyzed review evidence on a 1–5 scale; they are not laboratory measurements or a simple average of customer star ratings. Feature scores summarize the reviews covering that feature. The overall score averages feature scores within each review, then combines review averages. When both expert and customer evidence are available, those two groups receive equal weight. Products can have different review coverage, so small score gaps do not establish a winner.
Recommendations prioritize important features for the category, with a score of at least 3.5, a gap of at least 0.25 points and at least two supporting reviews per product. Features with widely varying scores or broad connectivity contexts are excluded from recommendations. These safeguards do not establish statistical significance.
Quick verdict
The review evidence points to a tradeoff: sleep tracking accuracy and recovery insights versus comfort and fitness tracking accuracy. Choose according to which strengths matter more to you; the overall score alone does not settle that choice.
Choose Polar Grit X2 Pro for sleep tracking accuracy and recovery insights.
Choose Polar Street X for comfort and fitness tracking accuracy.
