for the speed of getting the content to your pc... they can be the same, I guess torrents would be slower if you didn't cap your upload speed just liek dc++ would be slower if you never had enough sources to max the connection. But for speed of content distribution torrents kills everything. Because you are uploading while you're downloading you basically save alot of time and this is why torrents are used for piracy so much, its ideal you publish a film torrent and even if 56kers are on it with someone with a 1mbit conny the 1mbit guy will be able to get at full speed and then seed.
dc++ is good for local communities though because it takes less to setup and you just bring your stuff to the table to share. But remember stuff takes longer to get to dc++ than torrents, these days torrents are right under newsgroups in the distribution chain (topsite -> topsite -> ftpdump -> -> newsgroups -> torrents -> emule, kazaa, irc, dc++) and you'll find that alot of people with content on dc++ probably got it from another source like torrents
