Founders who use AI daily have stopped asking "which one is best" and instead match the tool to the task: Claude tends to win for writing, coding and thinking through strategy; ChatGPT is the best all-rounder with the strongest voice mode and app ecosystem; Gemini shines for research, live web answers and anything inside Google Workspace; Grok is mainly useful for real-time news and what's happening on X. The practical move is to pick one $20 daily driver, then run your actual work (an investor email, a landing page, a market question) through two or three of them for a week and keep whichever output you'd actually ship.
