I remember years ago seeing a study that diligently compared the factual accuracy of Britannica vs Wikipedia for a few select articles (will update this post w/link if I find it).
They found a similar rate of factual errors. The short of it: Wikipedia is chaotic and messy, but Britannica often had missing or out-of-date information. Wikipedia had higher noise, but also a higher correction rate. Factuality came out about a wash.
[UPDATE] I think it was this study: https://www.nature.com/articles/438900a
