How this comparison was built

Scores are medians across 124 audited Microsoft ASP.NET sites and 1 audited W3.CSS 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.

Small sample: one or both technologies have fewer than 10 audited sites. Treat these numbers as directional — medians stabilize around 20–30 audits per side.
