I’ll ask how will you finish the cab? If veneer, use the product with the better edge. I’ve veneered standard mdf and the flat packs supplied by Erich at diysg, and whatever Erich is using is far better as the edges don’t suck up 5 coats of contact cement. It makes for a smoother finishing project. I’d imagine if painting, it would be similar, as the edge will need less attention overall.
