How We Calculate This Score

Our objective rating combines Hardware Spec Quality (measuring real-world component power benchmarked across the entire category on a 1–10 scale) with a Price-to-Value Index (evaluating technical capability relative to selling price). User reviews and merchant sponsorships do not influence this score.
