There are many answers to your question, but the key is the quality of the product you need. I might as well tell you. There seems to be nothing in the showcase, but the woodworking materials and structure are very particular. Also pay attention to cracks in paint, primer and surface oil. But generally speaking, these cabinet carpenters you mentioned will stick protective boards on the surface of cabinets, and pay attention to the adhesion of glue and the treatment of corners.
