I don't understand the criticism of borg plywood for carcases and drawer boxes, if you're doing face frames and drawer fronts. When I remodeled our kitchen several years ago, that's what I used and it's holding up just fine. And some of the sides are exposed, like on the sides of the oven and frig. All of the panels here are that Sandeply I mentioned earlier.
And we've had a lot of compliments. No one sees voids in the plywood or the thickness of the veneer.
FWIW, I began cabinet building with high grade materials. But cabinets are not furniture. They are abused and taken for granted and when somebody tires of them or a new owner doesn't like them, they get demolished. So why dump extra money into something no one but yourself will ever appreciate?
