I tested ChatGPT vs Claude vs Gemini for coding ...here's what I found

So ive been going back and forth between these three for actual work (not just asking it to write fizzbuzz) and wanted to share what I found because most comparisons online are surface level garbage. Quick background: I do fullstack work, mostly React/Next.js with some Python backend stuff. I gave all three the same tasks over about 3 months of real daily use. Claude is the best for coding and its not even close imo. I had it refactor a 400 line React component into smaller pieces and it actually understood the architecture. kept all my tests passing too.
