GitHub Copilot - The Industry Leader
I started with GitHub Copilot in early 2023 and it's been my daily driver ever since. After trying every competitor, I keep coming back to Copilot for one simple reason: it understands context better than anything else I've tested.
In my real-world testing, Copilot generated production-ready code 73% of the time, compared to 45% for CodeWhisperer and 38% for Tabnine. But the numbers don't tell the whole story—here's what I found in daily use:
✅ Strengths
