ESLint
- Slow performance on large codebases compared to newer tools like Oxlint and Biome
- Complexity in configuration from scratch, particularly for TypeScript support
- Limited built-in TypeScript support, requiring separate parsers and coordination with new TypeScript features
GNU Emacs
- Steep learning curve for its default keybindings and Lisp-based configuration.
- Default UI looks dated compared to modern editors without heavy customization.
- Performance can lag on very large files compared to newer editors.
- Discoverability of features is poor without prior familiarity or external guides.
