Unless you fail to contact your peer because of no shared ciphers it is

-recommended to leave this option at the default setting. The default setting

-prefers ciphers with forward secrecy, disables anonymous authentication and
|
|
-disables known insecure ciphers like MD5, DES etc. This gives a grade A result
