Reposting my opinion from reddit
I'm reposting in essence what i said on reddit. The admins of a popular sub created a thread to give our opinions on a list of iq tests for accuracy and real iq was the highest in terms of performance and accuracy. Namely it ranked on top because of its length. The more questions, the more granular the results. We compared g-loading data and determined that this test correctly implements the The 2PL model.
