Safer yes, easier no. It is safer for two reasons:
1) You Usenet connection is generally encrypted, your connection to the torrent is not. This is why people say you should only use torrents if you're using a VPN.
2) Torrents are peer to peer. You upload to others as you download. Usenet is one way, you only download. When people are sued for tens of thousands of dollars while torrenting, it's done in civil court with the logic that every person you uploaded a part of the file too cost the movie studio a sale. So if you seeded a part of the torrent to 1,500 people and the movie costs $10 on itunes, they argue you cost them $15,000. If you were only downloading, you can at most be found liable for a single copy of the movie in civil court.
