My box is the step up from the smallest Masters Series that Snap-On makes, and while the largest Craftsman Pro-Line box is slightly larger, the actual storage space is smaller. The Drawers are not as large. I did alot of checking before I made my decision. The Snap-On box is also rated at more weight capacity, and I do actually have tools that require the full width drawers, which Craftsman does not offer.
BTW, Craftsman boxes are manufactured by Waterloo.
