Khaled: Are none of EFNet's servers properly SSL certified? Or are you only including networks with a proper maintained DNS round robin that reliably connects to an SSL capable server on a predictable port, using a common network-name domain name for each server?
One of the issues with the aforementioned networks is that they're typically administrated by a central authority or monarch with both first and final say in the running of all things and even the creation of channels or nature of allowable speech. All the other IRC networks are community effort adhoc peer networks with a very different ecosystem and chat experience. I don't know that these latter networks should be relegated as second-class no-go zones.
