I use two clients. ABC and Azureus....both of the have problems. The advantage of ABC is that it doesn't use a lot of resources when downloading, it makes 0kb files before downloading, but it still downloads batch torrents all at once. Azureus is good too, but the 2 problems that it has that I hate with all extreme prejudice is, 1)it doesn't make 0kb files for torrents that I haven't even downloaded yet!! for ex. let's say I download a batch torrent where there's 5 files and each file is 200mb's...what abc would do is just keep em all at 0kb/s until a fraction of them has been downloaded...what Azureus does is have it take up as much disk space as it would take up before even downloading! , and the one I hate the most, 2)it uses way too many flocken resources
