If you install the torrent one, then after that's installed do a restore you get asked to download the legal official one from Apple 🙂

once you have that, its the same one everyone else has 🙂
 
Torrents are not illegal.
In this case, it is. I use bittorrent only to download Linux distros, which is legal. But when you're bypassing copyrights and trying to get something for free which would otherwise carry a charge, you're breaking the law.
