Best for

Pick Copilot if your team is on GitHub + JetBrains and you need an enterprise-procurable AI coding tool.

Skip if

Skip it if you want the absolute leading-edge multi-file UX or to bring your own model API key.

GitHub Copilot pioneered AI autocomplete in editors and now ships with Copilot Chat, multi-file edits, and an agentic "workspace" mode that can take a GitHub issue from spec to PR. The integration with GitHub itself — PR review summaries, code explanations, issue triage — is the unique structural advantage no Cursor-class tool can match.

Model choice has caught up. Copilot now lets you pick between GPT, Claude, and OpenAI's reasoning models per request, which closes the gap with Cursor on a key axis. JetBrains support is first-class, which matters if your team isn't all on VS Code.

Where it still feels behind: the in-editor multi-file editing experience is slightly less ergonomic than Cursor's Composer, and the UX iterates more slowly. But for an enterprise with GitHub + JetBrains + compliance requirements, Copilot is often the only viable choice.

Editor's take

Copilot is the safe enterprise pick that's now legitimately good. It loses the bleeding-edge race to Cursor, but the GitHub-native integration and JetBrains support make it the only credible choice for many shops.
