I think both outputs are really good. I don't see a lot of differences. So what exactly should be looking at and notice that one model did worse or better than the other one.
EDIT: OKAY I see it's mostly the "image" generation, not so much the HTML... Noticeable in the food photos and the foodtruck/cart photo
clicking the add buttons and scrolling the menu is just much better in Opus 5. It feels like an actual website vs a simulation of one.
