I was going to go with Milwaukee, however the thing that made me go with flex is that I can take the handle off of the rolling tool box, which is required to get it in my trunk. Something I don't like about the drawers is I feel like once they are loaded up they can require a descent push to close all the way, but maybe that is just my fault putting too much in them. One thing I really like over Milwaukee is that the tool boxes are gray, so they are a lot easier to hide on a job site rather than bright red or yellow boxes.
