React Router outperforms Google Tag Manager in 5 of 7 categories, with a stronger composite score (75 vs 73). Google Tag Manager leads in no categories.
Google Tag Manager 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 security. Its audit data shows consistent strength in these areas across the sampled sites.
Scores are medians across 2547 audited Google Tag Manager sites and 142 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.
