I thought about making measurements on the number of subdomains that each tool retrieves and the number of information that they retrieve in general, but this poses several problems. In the end, these suites launch existing subdomain enumeration tools, so I'll do that other day (spoiler! 😲) and it doesn't really depend on the suite itself. On the other hand, each tool does different processes with different tools, so it would not be fair (or measurable, I think) to make a comparison of the quantity or quality of information they obtain.
