The short version

  • Each has a real cost: 7-Zip windows-centric GUI design; native graphical interface is Windows-only, with no first-class macOS or Linux GUI applications provided; WizTree it is free for personal use only, so deploying it across company machines without licences is a compliance problem rather than a saving.

Where each one falls short

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

7-Zip

  • Windows-centric GUI design; native graphical interface is Windows-only, with no first-class macOS or Linux GUI applications provided
  • Linux and macOS support primarily through command-line tools; no native file manager integration on these platforms
  • User interface design is dated compared to modern alternatives; visual feedback and UX polish lag behind commercial archivers
  • ARM64 support limited to Windows; no ARM64 build for Linux or macOS despite growing ARM adoption
  • No built-in cloud storage integration or synchronisation; cannot extract directly to Dropbox, OneDrive, or Google Drive

WizTree

  • It is free for personal use only, so deploying it across company machines without licences is a compliance problem rather than a saving.
  • The speed advantage exists only on local NTFS volumes; network shares, exFAT, FAT32 and ReFS fall back to ordinary directory scanning and lose the advantage entirely.
  • Reading the master file table requires administrator rights, so it cannot be used by standard users on managed machines without an elevation policy.
  • It is Windows only, with no macOS or Linux build, so a mixed estate needs a second tool anyway.
  • It analyses one machine at a time with no scheduling or central reporting, so it is a diagnostic tool rather than a way to manage storage across an organisation.

Answered from the vendors’ own pages

7-Zip: Is 7-Zip free to use commercially?

Yes. 7-Zip is licensed under GNU LGPL with BSD 3-clause portions, permitting commercial and personal use without fees, registration, or restrictions.

Source
WizTree: Why is it so much faster than other analysers?

It reads the NTFS master file table, the index the filesystem already maintains, instead of walking directories. It is one read of a structure rather than thousands of folder operations.

7-Zip: What file formats does 7-Zip support?

7-Zip natively creates 7z archives and supports packing/unpacking ZIP, GZIP, BZIP2, XZ, TAR, and WIM. It can unpack 30+ additional formats including RAR, ISO, DMG, and VirtualBox disk images without requiring external tools.

Source
WizTree: Can I use the free version at work?

No. The free build is licensed for personal use only, and business use requires a paid licence. WinDirStat and TreeSize Free are the no-cost options that allow commercial use.

7-Zip: Does 7-Zip work on macOS and Linux?

Yes. 7-Zip operates on Windows, Linux, and macOS. Graphical interfaces are optimised for Windows; Linux and macOS primarily use command-line tools. Port and third-party GUI applications extend functionality on these platforms.

Source
WizTree: Is it fast on network drives?

No. Master file table access needs local NTFS. Over a network share it scans conventionally and is no faster than the alternatives.

WizTree: Does it need administrator rights?

Yes, for master file table access. Without elevation it either cannot scan or falls back to the slow method.
