Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Rufus
- Windows only, with no macOS or Linux build
- Single-purpose: it writes drives and does nothing else
- Some of its Windows setup bypass options work around vendor requirements and may not survive future releases
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.

Answered from the vendors’ own pages
Rufus: Is Rufus free?
Yes, open source under the GPL.
Truecaller: How does Truecaller know who is calling me from an unsaved number?
It matches the number against a database built largely from other users' uploaded contact lists, plus spam reports from its user base.
Rufus: Does Rufus run on macOS or Linux?
No, it is Windows only. balenaEtcher is the usual cross-platform equivalent.
Truecaller: Can I remove my number from Truecaller if I never installed it?
Yes, Truecaller provides an unlisting search and removal tool at truecaller.com/unlisting, though you must find and use it yourself.
Rufus: Why choose Rufus over the built-in tools?
It is faster than most alternatives and gives explicit control over partition scheme and target system, which matters when a machine will not boot from default media.
Truecaller: Does Truecaller read my messages or call content?
Truecaller states it does not access call or message content, only caller ID and spam-reporting metadata.
