Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Deluge

  • It has no built in search tab, so finding torrents needs a separate tool, the same gap Transmission has against qBittorrent.
  • The default GTK client interface looks and feels less polished than qBittorrent fuller desktop application.
  • Getting the most out of Deluge, particularly plugins and remote daemon setup, requires more manual configuration than either rival.
  • As with any torrent client, legal use depends entirely on the content being downloaded, which the app does not moderate.
  • Plugin quality and maintenance varies since many are community contributed rather than officially supported.

Duplicati

  • No managed service or commercial support
  • Relies on community support
  • No enterprise features
