One of the many factors is ease of extraction of your components from the "cells" in the enclosure.

Presently, for reasons of density and cost, mostly, I use small plastic bags, with a built-in seal. I have a small box, and it's just a box, in which I keep the several hundred bags of components I have, and keeping them in proper order is the only inconvenience, since they are easily moved around, and, therefore, don't always find their way back to the correct position in the stack. I use large paper clips (the ones with a couple of handles and a capacity of aobut 2 cm.) to keep the stack segments in place, one per two decades.

Unfortunately, just as it's difficult to take just one 0403 capacitor out of a bin-box, it's also quite a difficult operation removing just one from a small plastic bag.

The one problem that seems most common with bin-boxes is that, when removing one component from a bin, it requires care not to drag along another and have it fall into an adjacent bin. Since SMT cap's are seldom labeled, that presents a contamination issue.

It seems simple enough at the outset, but component storage is a thorny issue once one begins to consider all factors.
