I used to use Azureus before i found Transmission. It's like comparing Acquisition to LimeWire. Limewire/Azureus is slow, nicely featured but written in Java (uck!). Tranmission has a wonderful Mac style interface and most of all is lean, not bloatware! I love it, and definately look forward to any future updates! #1 feature request is the ability to select files for download.
