Which has better accessibility, comScore or core-js?

Which is better for SEO, comScore or core-js?
comScore sites score higher on Lighthouse SEO signals (92 vs 91 on average), which cover meta tags, crawlability, mobile friendliness, and structured data. Content strategy and backlinks still matter more than platform choice for ranking.
