Have been using it for quite some time now and honestly I have found almost everything I searched for and once you set the router bandwidth properly, I was capable of downloading and seeding with 2MB/s. Satisfied my needs and gotta say not worrying about Letters coming to you is very calming

Ive been torrenting on I2P with qBittorrent for a lil while now, its not as fast as the clearnet, the fastest speed down ive ever got so far is 1.7MB/s, and this was on a torrent with loads of seeders. Its possible to increase your tunnel quantity and lower the amount of hops each tunnel has for better performance, but you will have less anonymity with less tunnel length.

But so far its been nice, there is no need to think about NAT/Firewall, as all peers can communicate with each other, but it doesnt have as much content as the clearnet, so I try to cross-seed what I can. But when im torrenting, I try to go I2P-first, and then fallback on the clearnet if I couldnt find what I was looking for.

I have not tried it myself but I found a paper that compares i2p to tor for latency/bandwidth. https://www.freehaven.net/anonbib/cache/ehlert2011:usability-comparison-i2p-tor.pdf

It's not how I normally torrent but it does seem to work okay. I've been experimenting with cross-seeding public torrents into I2P via qBittorrent 5.x (just using I2P, not torrenting publicly / no mixed mode / no need for VPN).

I've only picked up a few peers needing torrents I cross seed that way but otherwise does seem to work. Mainly the test torrents seem to get more hits e.g. seeding Ubuntu Linux ISOs so other people can test their torrent I2P setups.

I will add that currently I2P torrenting is a bit limited since Libtorrent itself does not support DHT via I2P so torrent clients like qBittorrent won't either. You always need to add I2P trackers to your torrents if you intend to torrent within I2P using qBittorrent or any Libtorrent based client.

The only torrent client that has the ability to torrent via DHT on I2P is I2P's own built-in torrent client (i2psnark) but that client has a lot of its own limitations, it's hard to use it as a primary torrent client.

How would you? It's supposed to be an enclosed system.
