I must confess that I have kept a couple. One for the track saw and one for the Domino. All others were sent to recycle heaven and these two are next. I do not do job site work and do mot need to tote my tools so fixed organization (drawers and custom fixtures) serve me best. I agree that it is subjective. If stack-ables and carry-ables work for you, then that is the right way to go.
