This Sephora is pretty good....it's the most convenient for me since it's the closest to where I live. Most products I need/want to buy they will have in stock. I don't really need someone weighing on me hand and foot so it doesn't bother me too much if a sales associate isn't asking me a million questions. I always get acknowledge when I first enter though. I'll tell you this, the customer service here is a heck lot better than the MAC store down the block. Sephora is always busy...no matter what time/day you go. Even on a Monday night...there was a long line at the check out counter. But everything was still processed smoothly.
Also, I much prefer Sephora over Ulta. My favorite Sephora store will be the one at Caesars Palace and I loveeeee my lip products!
