What are the best customized double ovens

So 30″ is pretty much the industry standard and if you just have one space, it’s always nice to do a double like the great GE Café french door https://www.cafeappliances.com/appliance/Cafe-Professional-Series-30-Smart-Built-In-Convection-French-Door-Double-Wall-Oven-CTD90FP2NS1. If you are looking for a multi use oven air fry convection speed bake and are short on space the Café with the  Advantium combo  https://www.cafeappliances.com/appliance/Cafe-30-in-Combination-Double-Wall-Oven-with-Convection-and-Advantium-Technology-CTC912P2NS1is an amazing piece as well. If I was doing it, I might say go for the BlueStar double oven French door in a custom color with custom bezels. Real sharp piece!  Café is my go to piece these days for wall ovens. If you want to get into steam etc stacked units I would take a look at the Miele line as well.
