Usenet is less risky than torrents, because you will never need to upload anything. You will never get a letter from your ISP or any lawyer.
Usenet can max out your internet connection (instantly). So you can download with full speed.
You do not need to worry about your upload ratio.
You can fully automate your usenet setup.
No need to get an invite to a private torrent. NZB Indexer like nzbwolf.com are open to anybody.
With Usenet you pretty much fly under the radar, most people are using streaming or torrents.
