Reviewers mostly see GitHub Copilot as a strong, always-on coding assistant that fits naturally inside editors, speeds up boilerplate, follows local patterns, and helps developers stay in flow, learn syntax, and move faster across languages and frameworks. Several say it has improved notably, with some finding it useful on larger or mature codebases. The main criticism is reliability: suggestions can be generic, buggy, or confidently wrong, and bigger project-specific or multi-file tasks still seem better handled by tools like Cursor or Claude Code.
