Tor is a popular mixnet, maintaining high censorship resistance and preserving privacy. However, it is highly centralized with directory authorities, leaving it with failures. Additionally, communication is limited in Tor. 

Tor - The Onion Router

I2P maintains a higher level of trust agility by referring to a distributed hashing table instead of directory authorities to ascertain the network state. However, it has not had a steady developmental process and has problems ranging from lack of support for exit nodes to users becoming routers, increasing bandwidth requirements.

LLARP operates without directory authorities, and relies on a DHGT built from blockchain staking transactions, allowing service nodes to act as routers. LLARP provides an anonymous network layer by supporting a larger range of internet protocols and minimizing the overhead for storing file descriptors. End users are not allowed to route packets, lessening Lokinet's exposure to attacks.

Service nodes are underlaid with an anonymous routing protocol, defining the way each service node communicates with its peers. Loki uses a hybrid of Tor and I2P for their protocol.
