Where each one falls short

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

qBittorrent

  • It lacks true thin-client remote operation, so controlling a qBittorrent instance running on another machine is less seamless than with Deluge without relying on third party tools.
  • The web UI can start to lag once active torrent counts climb past roughly a thousand, which matters for a heavy seedbox user.
  • It generally uses more resources than Transmission for the same workload, which matters on a low powered NAS or always-on server.
  • As with any torrent client, legal use depends entirely on what content is being downloaded, and the app itself has no content moderation.
  • Its default interface, while functional, is denser and less minimal than Transmission simple design, which some users find harder to learn at first.

Truecaller

  • Its caller ID database is built from other users uploading their contact books, which means a person's name and number can be listed without them ever installing or consenting to Truecaller directly.
  • Removing a number requires actively finding and using the unlisting tool; it is opt-out, not opt-in, so most people never realise they need to do this.
  • The free tier is ad-supported, and ads appear on the call screen itself, which some users find intrusive during otherwise mundane phone use.
  • Call recording availability depends on local law and has been restricted or removed in some regions and OS versions, so it cannot be relied on everywhere.
  • Regulatory and app-store scrutiny of the contact-upload model has led to restrictions or bans in some countries, so availability and feature set are not consistent globally.

It matches the number against a database built largely from other users' uploaded contact lists, plus spam reports from its user base.

Yes, Truecaller provides an unlisting search and removal tool at truecaller.com/unlisting, though you must find and use it yourself.

Yes, via its web UI, though Deluge specific thin-client mode gives more complete remote control for a dedicated daemon setup.
