These tools aren't interchangeable. GitHub Copilot predicts what you're about to type. Cursor forks VS Code with chat, inline edits, and codebase search. Claude Code is a terminal agent that works through multi-step tasks: editing files, running commands, writing tests, and opening PRs.
Claude Code has no inline autocomplete. You work at the task level, not the keypress level. I use Copilot to finish a line, Cursor to rewrite a function, and Claude Code to refactor a module end to end.
