React Router outperforms Microsoft in 5 of 7 categories, with a stronger composite score (75 vs 72). Microsoft leads in no categories.
Microsoft doesn't clearly lead React Router in any category on the sampled sites — pick it based on developer experience, ecosystem, or existing team skills rather than the audit scores.
Choose React Router when your primary concern is server response time and SEO. Its audit data shows consistent strength in these areas across the sampled sites.
Scores are medians across 2412 audited Microsoft sites and 134 audited React Router sites in the BeaverCheck database. Every audit runs the same 100+ checks — Lighthouse performance, security headers, accessibility, SEO, server response time — against a real URL. No vendor input, no sponsorship, no affiliate links.
