SSL Labs is the gold standard for grading a single TLS configuration. AcuityScan checks your SSL alongside seven other categories, so you see the whole site's health, not just the certificate.
SSL Labs (by Qualys) produces the most respected deep-dive grade for a single TLS endpoint, and it's free. If you're hardening one server's cipher suite and want the canonical A+ assessment, use it. AcuityScan reads your SSL and security headers as one part of a full-site audit, then ties them into a single health score with the rest of your stack.
