I looked very hard at this shack last year when I was shopping for a new one. I've never been very brand specific, but for the most part always owned Frabil. When this came out I loved the idea of the side doors and the flat front. With that being said, I did a lot of home work and took A LOT of trips to Cabelas before pulling the trigger on a new shack.
I would say you really need to consider how you will be using it. By that I mean how your towin it, storing it, transporting it. Will all of these things considered I ended up buying the Clam Voyager TCX. They are roughly the same fishable area, the Clam is a little taller, but most of all the Clam is lighter. I'm usually loading and unloading my shack by myself. I also still need the ability to walk it out from time to time. I really needed to consider all of these factors. On top of that I think Clam has better stock features and they offer a ton of really useful accessories.
Not trying to promote one over the other. Just giving you my experience last year when faced with buying a new one. Most of all, I would say check them all out in great detail before making a purchase.
