As others said, the best skins depends on each person as we each have different taste.
I, myself, am a skin addict, like i am with hair & clothes (oddly not shoes lol). I get complemented a lot from ppl around me on the skins I find. My secret....lots of searching. I always start with marketplace. It takes time, but I always end up overly satisfied with what I found. many times I find a brand new designer that has AWESOME skins, before they ever become popular. Places like LAQ, Curio, and such do have good skins, but are too popular for me. I like to be as unique as i can be, and half the women i see have LAQ skins now it seems, just like when RedQueen was the most popular, everybody had it. I also feel that, for the price comparison, depending on what you're willing to spend and how many make-up differences you want, you can find some just as good or better for a lot cheaper. So, my advice, take some time to search the Marketplace pages of skins, get a lot of demos, visit some stores, until you're happy with what you've found, that's how i always find the best deals
