UIKit outperforms Microsoft in 5 of 7 categories, with a stronger composite score (74 vs 72). Microsoft leads in security, TTFB.
Choose Microsoft when your primary concern is server response time and security. Its audit data shows consistent strength in these areas across the sampled sites.
Choose UIKit when your primary concern is performance and best practices. Its audit data shows consistent strength in these areas across the sampled sites.
Scores are medians across 2421 audited Microsoft sites and 9 audited UIKit 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.
