Both scored close to 8.0/10, so the better choice depends on your priorities. Safety carries 50% of our scoring weight, followed by performance (20%), usability (20%), and value (10%). Check which pillar matters most to your family and compare those specific scores.
We use our V4.2 deterministic rubric with four weighted pillars: Safety (50%), Efficacy (20%), Usability (20%), and Value (10%). Every score is reproducible - the same product data produces the same score. Each product is evaluated across multiple criteria within each pillar.
Not necessarily. The overall score reflects our weighted rubric, but your priorities may differ. If you care most about safety, compare the safety scores directly. If budget drives your decision, the value scores and prices tell a clearer story. The "right" pick is the one that matches what matters most to your family.
