SZ is the lowest cost per year of use.

You can’t have both - either they’re built-in, paneled and hidden (the correct terminology is ”fully-integrated”), OR it’s economical. If you remove the word ”hidden” from your want-list, you can come down a bit in price. The built-in fridge (but not fully-integrated) will be visible as a fridge but it will be paneled to match your cabinetry. Still it won’t be economical - panel-ready appliances are higher-priced than non-panel-ready appliances, and don’t forget you have to pay for the panels too.

I appreciate your response! I guess the panel looks like a seamless kitchen which is why I like it. The fully integrated is nice, especially if the refrigerator is pretty.

If you like the seamless hidden look—and many people do and are willing to pay for it—the Subzero and Miele brands are beautiful. Again, these will not be at all economical.

If I had to make a choice based on budget, I'd sacrifice somewhere else and get the SubZ. Gorgeous looks aside, food will stay fresher much longer. SubZ/Wolf appliances are in my experience bullet proof. Expensive, yes, and worth every penny from an aesthetic and functional perspective.
