I had my Pogonomyrmex colony in atom nest and they enjoyed. I understand the atom nest are for founding colonies. Probably not what you are looking for. Like what Dakota said dirt or some "rocky" sand will probably work great.
I think I saw someone with some Dirt formicariums good for Pogonomyrmex. I think it was Drew, but I can't recall well.
Tar heel ant's labyrinth looks amazing. It provides a nice size for the colony to grow. Antstower also has the possibility to look nice with a natural feel. Dirt or another digging medium can be appealing to the colony. They are both good options I'd say.
The antstower can make it easier for cleaning when you get rid of your Pogonomyrmex colony I suppose.
I would also have a hard time choosing, but the tar heel asethetics just win me over.
I didn't really provide much informative help, just my thoughts. So here are some thoughts. I guess the antstower would allow colony to build Chambers as they grow, which can reduce the chance of the ants just having a giant trash bin, but with workers I wouldn't see this as a big issue. I feel there might be a gamble on the antstower with the asethetics of the chambers, since the colony won't really focus on design. Tar heel ants already have a nice set design. I feel like that antstower allows for more creative design, but the tar heels provide a very appealing set design. If you feel being creative the antstower might be a good fit.
I hope your purchase goes well.
P.S Pogonomyrmex being terrible climbers is something that helps me sleep at night.
