A lot of people on this forum seem to think that it's AMAZING, but I've been twice, and only came back purchasing something once. I looked into a few of the higher end stores (Chanel, Balenciaga, etc) and they seemed.... empty? I like Saks off 5th, but they have those a lot of places.... I also liked the Diane Von Furstenberg and Tory Burch stores. The DVF store had some pretty good deals in the sale section....
To answer your question, I think its similar to other "premium outlets" but I also don't spend a lot of money on high end things so if I had more money, it might be worth it....
if you're wondering about any specific store, it's only about 1 hour away from me, and i just went last tuesday, so i can remember a lot....
