The interesting question for me is what are the advantages of running the node over I2P instead of Tor. I haven't really looked into it.
I 've read about the I2P protocol in the past and, from what I 've read:
1. The obvious difference is that on I2P you can only connect with I2P, whereas a Tor node can connect (potentially) to clearnet as well.
2. Privacy-wise I2P must be superior.
I have no idea about speed, latency, reachability etc.
