I2p engineering is superior to Tor. It has no exit notes. I think of i2p as a support network from the plain open internet. Tor can access .com and .org sites, i2p only works within the i2p framework and has no access to anything outside of i2p or eep sites.
I don't use it because there's nothing on there, but I still strongly support it and prefer it over Tor or .onion
I quit running i2p so others have access to my bandwidth because of always having to adjust settings for network being firewalled, otherwise I would leave it running permanently but it's always firewalled on a new setup.
