Facebook outperforms Sizmek in 5 of 7 categories, with a stronger composite score (72 vs 72). Sizmek leads in no categories.
Choose Facebook when your primary concern is server response time and performance. Its audit data shows consistent strength in these areas across the sampled sites.
Sizmek doesn't clearly lead Facebook in any category on the sampled sites — pick it based on developer experience, ecosystem, or existing team skills rather than the audit scores.
Scores are medians across 1407 audited Facebook sites and 3 audited Sizmek 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.
