The verdict
There's no loser here, only a fit. ChatGPT is the safer single pick for a founder who wants one tool to write, research and produce the odd image, and it lets you pay in below 20 USD. Claude is the better engine when the work is serious drafting, analysis or coding and you need a whole document in context at once, with a 200K-token chat window (1M on the API) against ChatGPT's 128K.\n\nMy honest take for a lean B2B team: they're cheap enough relative to the hours they save that running both is defensible, ChatGPT for breadth and images, Claude for deep writing and code. Forced to one, decide by your dominant task, not by the brand.
