The short version

  • Only Eclipse IDE has a free tier, so it costs nothing to try first.
  • Each has a real cost: Eclipse IDE startup time and UI responsiveness lag behind newer editors like VS Code.; GitHub Copilot agent mode lacks deep tool orchestration and iterative execution compared to specialized agentic tools
  • They diverge on capability: Eclipse IDE covers Java Development Tools (JDT), GitHub Copilot covers Code completion.
