Classic 96 has been perfect for my home use. Do you think you are going to exceed 120 pounds with the drawer configuration? I would have a hard time maxing out the shallower drawers with the configuration I have- the deep socket drawer has double-slides or that may be where I would have an issue.
If you need the extra weight capacity, you may have your answer. I can't comment on the specifics of the Matco since I have never touched one.
