He probably just went to the kitchen studio, stated his budget, laid down the plan with the G, and said that’s what he wants. His practical kitchen experience up to that point came from his parents and a few rental apartments.
Even though it is "preached" again and again, the prevailing idea is to show the OP more practical options. This includes, for example, a better hood, a 6-step grid if you have a certain height, and the fact that not every kitchen shape brings joy over the years, especially if there are 5 people. But nobody tells you that in the studio, where the kitchen retailer is under time and sales pressure, especially in the "cheaper" price segment. A kitchen is used most like a bed. I do think it’s worth spending something on the kitchen furniture so you have more and better storage space, more work surface, and easy-care fronts. With the appliances, that’s less important; the kitchen will still be there when the appliances have already been replaced several times.
But for most, it has to be a cooking island, a Dekton countertop (which breaks faster than all others), a handle profile because everyone else has it even though it’s more expensive and offers worse storage space. Everyone does the same, herd behavior, just not doing something different. If everyone does it, it has to be right.
