Lenox Square Mall vs. Phipps Plaza ... whats the difference?

Lenox Square is a fancy mall that has a nice variety of prestigious stores (like Louis Vuitton and FENDI), but it also has a lot of your average popular mainstream stores (like Gap, Forever 21 and Macy's). To me, Phipps Plaza is more of a luxurious mall. Mostly, all of the stores in Phipps are top of the line (Gucci, Tiffany & Co., Barneys New York Co-op, and so on). The funny thing is they are both practically right across the street from each other. So, if you can't find what you are looking for at one... you can always check the other :)
