450kb/s with torrents
490kb/s with Newsgroups
I prefer newsgroups, no shitty sharing, almost always complete or repairable and the downloads use your maximum bandwidth from beginning till end. Drawbacks are that you have to have a decent retention and that you have to request some anime to be upped, not that that is much of a problem.
