The big difference between #pubky censorship-resistance and all others is that #pubkey is verifiable.  It has a 15 year track record, millions of nodes, and simple, easy to run software, because it uses the existing proven bittorrent network.  No other network is close to this, or will ever come close to this.  Other claims of censorship-resistance are "trust, cant verify".  #pubky is "verify, dont trust".
