The ones that I think are the best are..
Face
187 - I use this to apply my foundation and everytime it looks soo flawless
168 - I use this to contour and to put on blush
If u want a brush for contouring I think this is your best bet
Eyes
239 - As everyone says this is great for packing on colour, I always use this brush its great
219 - This is a great brush for use on the lower lash line
and in the inner corners
217 - This is a great blending brush, also great for the crease and outer v
266 - I use this for eyeliner and brows
I dont own any lip brushes but I like the look of the 316
Hope this helps
