My new house had a bunch of Gladiator track installed in from the previous owner. It seemed logical to go with this flavor of wall cabinet.
I inadvertently ended up with both the cheap and the premium versions though. I originally ordered the cheap 'ready to assemble' versions from Overstock, but soon noticed the ship date was 2-3 weeks out. I also saw Home Depot had the premium line with 2 day shipping, so I ordered those and cancelled the Overstock order. Sure enough, overstock claimed they were unable to cancel it and shipped it anyway a few days later. At that I point I just decided to take the Pepsi challenge.

The cheap ones ship packed very tightly. This is 6 of them.
No photo, but the premiums obviously ship full sized plus a few inches per side.
On paper, they're nearly identical, but side by side the difference is more noticeable than I expected.
28x28 vs 30x30
The magnet catch is single one on the shelf, vs full magnetic strips on the top/bottom edges.
Honestly I was fine with the single magnet. The larger door closed and released with slightly more authority, but it wasn't a big difference.
The biggest design difference is the floor. The small one has downward bent flanges, while the large is reversed. This gives the large cabinet and 2 more inches of height, but with a lip you have to go over. So interior volume is closer to 28x28 vs 30x32.
The smaller ones have a office style wire passthrough. I was surprised to see the cheap on have an additional feature that the premium did not.
Thickness differences surprised me. The cheaper ones felt reasonable stiff, and I questioned weather the premiums were actually thicker gauge or not. Clearly my hands are not calibrated for this.
Take these values with a grain of salt. I did not put much effort to square up the calipers and there are likely paint thickness variances.
I forgot to get a side by side photo, but the cheap ones have a single channel to hang from, while the premiums have 2 channels, top and bottom. The lower channel on the premiums is in a slotted vertical hole so you can adjust to account for track installation error.
Load ratings are 150 lbs vs 200 lbs.
The load sharing on the two premium channels is only going to be as good as your installation method, but I suspect if you install them carefully you could load this thing easily to 300+.
The cheap ones are easy to hang. The premiums require a bit of finesse but nothing major.
The track location is indexed to alight the tops of both versions if you mix them. If you want the lower to align, you'll have to jog the wall tracks.
