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
FreeFileSync
- The interface is dense and functional rather than friendly, and the sync direction is easy to misread
- Some convenience features are held behind the paid Donation Edition
- The installer has historically bundled optional offers, which is worth reading carefully during setup
- Not a versioned cloud backup: it synchronises what you point it at and nothing more
