Which Tool Should You Choose?

Choose GitHub Copilot If:

• You want the most affordable option ($10/month)
• You need JetBrains or non-VS Code editors
• Your team is already on GitHub Enterprise
• You primarily need autocomplete-style suggestions

Choose Cursor If:

• You do a lot of multi-file editing
• You want agent mode for autonomous changes
• You're comfortable with a standalone IDE
• Speed is your top priority

Choose Claude Code If:

• You handle complex debugging and architecture
• You need to understand unfamiliar codebases
• Code quality matters more than speed
• You want reasoning, not just suggestions

The Stack We Use at Buun Group

We don't pick just one. Here's our actual workflow:

Bottom Line

For most developers: Start with GitHub Copilot at $10/month. It's the lowest-risk entry point with the widest IDE support.

For serious development: Add Cursor for $20/month. The agent mode and Composer pay for themselves in time saved.

For complex work: Use Claude Code for architecture decisions, debugging, and code review. Its 80.9% SWE-bench score and "Most Admired LLM" status speak for themselves.

The winning strategy: Use all three for what they're best at. $50/month total for a complete AI development stack is a small price for 2-3x productivity gains.
