Microsoft outperforms Highcharts in 6 of 7 categories, with a stronger composite score (72 vs 71). Highcharts leads in no categories.
Highcharts doesn't clearly lead Microsoft in any category on the sampled sites — pick it based on developer experience, ecosystem, or existing team skills rather than the audit scores.
Choose Microsoft when your primary concern is server response time and accessibility. Its audit data shows consistent strength in these areas across the sampled sites.
Scores are medians across 11 audited Highcharts sites and 2328 audited Microsoft 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.
