Vuze adds a social component to it among other things. Users can for instance add friends to the client and prioritize this traffic and share torrents with their friends easily. A torrent search engine is included as well in the client with the option to add other search engines that are not listed yet.

The old user base that was happy with just the Bittorrent client is at least partially unhappy with the decision. Many users will continue using the old Azureus client or start using another client like uTorrent.

While the old interface of Azureus is still available in Vuze users will have no way of downloading the Bittorrent client without the additions implemented by Vuze.
