I uploaded a web design of mine (jpeg) and asked Claude to create the html/css. Asked GPT to do the same. GPT's code looked the closet to the design I created and uploaded. Just five to ten small tweaks and I was done vs. Claude it would have taken me almost triple the steps.
I actually subscribed to both today (resubscribed to GPT) and going to keep testing which one is the better front-end developer (i am, but got to embrace AI ).
