Pros & Cons
ChatGPT
- Largest user base and ecosystem of any AI assistant, with the most third-party integrations
- Genuinely broad capability across writing, coding, research, and file analysis
- Custom GPTs allow tailoring the assistant to specific repeated tasks
- Frequent model updates keep it competitive on raw capability
- Free tier has usage limits and access to a lower-tier model than paid plans
- Can produce confident-sounding but incorrect information, especially without browsing enabled
- Breadth can mean less depth than a tool purpose-built for one specific workflow
- Data usage and training policies require attention for sensitive or regulated work
ECC
- Massive community adoption — over 200,000 GitHub stars and 170+ contributors
- Genuinely solves cross-tool configuration fragmentation for developers using multiple AI coding assistants
- Free tier available for public repo analysis before committing to a paid plan
- Full-depth support is strongest for Claude Code, with other harnesses receiving capability-limited adapters
- Private repo analysis and higher usage limits require the paid Pro tier
- Fast-moving space means ECC and its supported harnesses will likely keep evolving quickly
