Quick Verdict
Choose Sublime Text if you prioritize raw speed, stability, and a polished, distraction-free experience. Choose Atom if you value deep customization, open-source extensibility, and are comfortable with a web-based architecture, especially for web development.

Atom is an open-source editor built on Electron, offering unparalleled hackability through web technologies but with higher resource usage. Their core difference lies in philosophy: Sublime prioritizes speed and efficiency, while Atom prioritizes community-driven customization and modern extensibility. This leads to different target audiences, with Sublime appealing to performance-focused generalists and Atom historically attracting web developers seeking a tailored, IDE-like workspace.
