Cursor vs GitHub Copilot: What I Actually Switched To

I was a Copilot loyalist. Paid for it since the early beta, recommended it to everyone. Then Cursor 0.40 dropped and my team started talking about it constantly. I gave it a real month-long trial instead of the usual two-day test-and-abandon cycle.

Here's what I found.

What Copilot Still Does Better

Ghost text completion feels more natural in Copilot. The inline suggestions appear faster and feel less intrusive. When you just want to keep coding and have suggestions quietly filling in the blanks, Copilot's UX is slightly smoother. It's also embedded directly in VS Code proper, so there's no app switching.

For snippets, small utility functions, and test cases, both tools are roughly equivalent. The completions are similarly good. Copilot's advantage here is familiarity — if you've trained your muscle memory to accept/reject completions, you don't have to relearn anything.

Where Cursor Pulls Ahead

The Composer feature. This is what changed how I work. Instead of asking AI to complete a line, you describe what you want across your entire project. "Add error handling to all API routes" — and it touches six files, not just the one open.

Cursor also understands your codebase context. When I'm working on a React component and ask it to add a feature, it actually reads the types from my other files instead of inventing new ones. Copilot mostly works on the open file. Cursor reasons about the project.

The chat interface (Cmd+L) lets you ask questions about your code, get explanations, or have it write code while referencing specific files you point to. This is just different from what Copilot offers.

The Actual Speed Difference

I tracked my time for two weeks each. On pure line completion speed, almost identical. On larger tasks — writing a new API endpoint end-to-end, adding a feature to an existing module, refactoring a component — Cursor saved me 20-30 minutes per task. Not every time, but consistently enough to notice.

The Problems With Cursor

It crashes more than VS Code. Not constantly, but noticeably. The AI sometimes goes off-script on large edits and you have to carefully review every change. The free tier runs out fast if you use Composer heavily. And some VS Code extensions have subtle quirks in Cursor that you only notice after weeks of use.

My Take

Cursor is a better tool for larger projects and longer coding sessions. Copilot is better for quick, focused coding in VS Code where you want minimal distraction. I switched to Cursor full-time. My teammates who work on smaller, well-defined projects stuck with Copilot and that's a reasonable call.
