The crossover is around a dozen balls at a time. Almost nobody reading this makes a dozen balls at a time.

A dough box is a shallow rectangular tray sized so that a row of balls sits in it with a lid on top and another box stacks above. It exists to store many balls in minimum vertical space, and it is very good at that.
Individual containers hold one ball each. They cost more shelf area for the same number of balls and give you complete independence - take one out, leave the rest, different doughs in different tubs.
| Balls at a time | Better option | Why |
|---|---|---|
| 1-2 | Individual tubs | A tray is mostly empty and still occupies its full footprint |
| 3-4 | Either | Four tubs is about the same shelf area as one shallow tray |
| 5-12 | Shallow tray | Stacking wins decisively past four |
| 12+ | Proper dough box | And check your shelf width first - most are 25 inches or more |

Height of a domestic-sized dough tray against a commercial dough box
Almost identical. The difference that matters is width: 16.7 inches against 25 5/8. One fits a fridge shelf and one does not.
Searching for a dough proofing box returns commercial equipment, because commercial equipment is what the term describes. Those listings publish their dimensions honestly, and the dimensions are for a walk-in.
The Winco PL-3N in most published lists is 25 5/8 by 18 by 3 1/4 inches. A standard 36-inch American fridge has about 18 inches of usable shelf depth, so it goes in one orientation only, on a completely clear shelf. It is a good box. It is not a domestic box.
Marginally, and in one specific way: shape. A ball in a tall narrow tub is constrained sideways and rises into a dome. A ball in a wide shallow container relaxes into a disc, which is closer to what you want when you come to stretch it.
Beyond shape, no. Material makes no difference to the ferment - a fridge equalizes everything within an hour or two regardless of what the walls are made of. Clear versus opaque changes what you can see, not what happens.
One genuine advantage to individual tubs: balls proofing in a shared tray grow into each other, and separating two joined balls degasses both. Leave a ball's width between them.
Two balls a week: two 2-quart round tubs. They fit any shelf, you can read the ferment through the wall, and there is nothing to store when they are empty.
Four to eight balls: a shallow stackable tray of domestic width, around 3.5 inches deep.
A dozen or more, regularly: a commercial dough box - and measure the shelf before you order, because the listings are honest and the numbers are large.
We have not baked on any of these. Every guide in this category says it tested a dozen stones; we would rather say plainly that we did not. What we did instead is on this page in full: published specs with their sources, thermal arithmetic from material constants with the working shown, and the makers' own manuals read rather than paraphrased.
Ooni
Shallow, stackable and 3.7 inches tall, which makes this the only dough box here that clears a domestic fridge shelf. The maker publishes both the dimensions and the dough-ball count, which is more than the restaurant-supply options manage.

Cambro
The same unbreakable polycarbonate as the 6-quart everyone recommends, at 4 3/16 inches tall instead of nearly 11. One ball per tub, and it fits.

Winco
This is the box every proofing-box guide recommends, and it is 25 5/8 inches wide. That is wider than most domestic fridge shelves are deep. We list it so you can see the trap before you fall into it.
