I was in the same situation as you. I have a snap on box that loaded and I needed more space. I bought the HF 56" top and bottom and I am pleased with it. I would have went with the 72 but room was an issue with where I wanted to place the box. Is it comparable to a snap on box, no, not in quality or in price. I don't think you could park a dump truck on the top of these boxes like SO does in one of their ads and I haven't tried standing in one of the open drawers. Luckily for me I didn't need the box to store dump trucks and I already had a ladder to stand on if I needed to reach something high. If money was no object I would have another SO box in my garage but for the money paid I am happy. I like the layout and it holds everything I need it to. The latch mechanism isn't the greatest but for home use it really doesn't matter to me. The liners aren't the best but depending what you want to spend you could line the drawers with gold if you wanted to. I am using the supplied liners with no complaints. If they become a problem in the future I will upgrade them at that time. For me if I could go back I would make the same decision and buy it again. I have the bottom drawer stuffed with brass, copper, aluminum and steel round, flat and square stock which I am certain is over the recommended limits of the box and it still opens and closes with ease. Fit and finish are good. I took all the drawers out when I got the boxes as the drawer slides seemed to be a little dry and had some contamination. I cleaned them up and lubed all of them and they worked perfectly after that. Other than that No complaints. Open the shipping boxes up while at HF because it seems like a few people have found some damage once they got home and removed the packaging material with anything from dings and dents to complete corners being crushed. The money saved can help fill the box up.
