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

Spline

  • AI generation features produce inconsistent and often distorted results, failing at basic depth perception tasks
  • Limited to simpler designs - not suitable for high-poly, detailed production models
  • Performance degrades with complex scenes containing many objects and materials
  • Limited non-Apple platform coverage compared to cross-platform design tools
  • Tutorials are either too fast for beginners or too basic for advanced users
