if your willing to pay for one of the more expensive ones, the MAC one wins hands down. like lara mentioned, it has nothing to do with brand loyalty, its simply just the best brush, taking into consideration price, quality, size, functionality, and durability. the prescriptives one felt so wierd, and when i played with it at the counter, it seemed cheaper and flimsy, plus i thought the handle felt wierd. the lancome barely seemed like a stippling/skunk brush, and more like a glorified blush brush, with no extra qualities. the MAC one really is the best face brush i've come accross, as it is so good for both cream and powder products, and is easy to control, as far as where you want the product placed. it seems to be holding up well, i have two, both of which are used daily, and cleaned often, and both are in fine shape. the flirt is an okay alternative, but realize you will never get the same quality in a $42 brush, and a $6. i have a few of the flirt ones, and they're good for practice/travel/whatever. if you go into the flirt brush with 187-level expectations, you will be disappointed.
