Reviewers mostly see GitHub Copilot as a strong, low-friction coding assistant that fits naturally inside the editor, speeds up boilerplate, autocomplete, and repetitive work, and often helps with learning, debugging, and staying in flow. Several say it has improved noticeably and works well with mature codebases or familiar patterns. The main caveat is reliability: suggestions can be wrong, generic, buggy, or need refinement, especially on project-specific logic or bigger multi-file tasks, where some reviewers still prefer tools like Cursor or Claude Code.
