I can fit about 20 lbs (1/2 square bale) in a small hole hay net from Chick's Saddlery. I know this wasn't your question, but they are less expensive than the ones you mentioned, and can fit the amount of hay that you would like.
For a whole bale, those wouldn't work, but 1/2 bale, definitely.

I like the whole bale Cinchchix nets for my run-ins because you can put the bale in there and cut the strings after it is hanging. That takes a lot less time that stuffing flake by flake. And I only have to do it every other day.
If I were in a stall situation I would get XL Nibblenets. I have those in all my stalls and they are the easiest to operate. it takes me an extra 30 seconds to load them -- carry hay in stall, unsnap front half of NN, drop hay in, snap. So easy. I don't even have to take them off the wall.
I have 2 freedom feeders as well and they developed holes within the first week of use. They are not sturdy enough, IMO.
Freedom Feeders are way easier to load and once the horses get used to the slow feed system, they hold up well. I did have a couple holes when first introduced, they were easy to patch, and have held up since. When the horses are first using nets they are harder on them until they figure out pulling they hay through. The CC is heavier duty netting, but harder to fill. To the point that husband refused to use the CC but is happy to use freedom feeders. We now have freedom feeder extended day in our stalls and have made big portable slow feeders for turnout out of Equine Hay Baskets and hockey netting. These hold four bales at a time and are easy to fill. I've also used the SMHN from Chick's, Dovers, and Nibblenets. All of those wore out over time and none are as easy for us to fill as the FF Extended Day and out big hay baskets.
