1. Trackerless torrents
In 2005 all the popular clients included DHT layer support (Distributed Hash Table). These DHT layers “decentralize” torrents what make them more stable and less reliant on the web based trackers. If a web based tracker goes down, the torrents stay alive because several peers can act as “nodes” keeping the swarm intact (this may sound vague, but trust me, it works).
Clients that support DHT are: Azureus, Bitcomet, Bitspirit, BitTorrent official, Shareaza, Turbotorrent and uTorrent.
2. uTorrent
uTorrent has all the advanced feature you need, but uses less cpu and memory. Within a couple of months uTorrent has become one of the most popular torrent clients along with Azureus and Bitcomet.
