Where each one falls short

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

Eclipse IDE

  • Startup time and UI responsiveness lag behind newer editors like VS Code
  • Plugin quality and compatibility can be inconsistent across versions
  • Modern language support (e.g. for web frameworks) is weaker than dedicated tools
  • Configuration and workspace setup has a steeper learning curve for newcomers

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
