I've used heavily I2P and Freenet both. To answer your question, better? Neither I2P nor Freenet claim to be inherently better than the other. It depends entirely on what you are using Freenet or I2P for. I2P is like Tor but internal (it does not mainly anonymize clearnet traffic, think onionland) and it is anonymous by default. How anonymous? Theoretically as anonymous as Tor. You can use I2P for torrents and filesharing, pretty fast irc, etc. To host an eepsite (I2P site) you have to run a server and keep it running as long as you want the site to be up, similar to running a Tor hidden service or any server on the clearnet. Freenet has a lot more static content (no JavaScript), reminds one of the early internet (in a good way, mostly). Hosting of freesites (Freenet sites) and files is distributed, no need to run a server to have your site up. There is no 'delete' button on Freenet either. Files/ sites are deleted when no one accesses them for a time. Popular content stays forever. Sites under 2MB in size typically stay forever. Freenet is not anonymous by default, you need to know people IRL who use it to create a friend-to-friend darknet for it to be anonymous. I use mine with a VPN. Both networks are great, lots of cool people use them. I use FMS a lot (Freenet Message System, similar to Usenet) and Sone. When I use I2P I usually host a few eepsites and hang around Irc2p (I2P's irc). I recommend installing and using both. They're both great.
