I think it would be helpful to know what you are looking for? Do you want a versatile brush that can apply cream, liquid and powder foundation? Are you interested in a brush that gives you light coverage you can build up to your desired coverage or do you want full coverage with just a few quik strokes?
For example, the 109 gives you an amazing look and you can use it with any type of foundation, but it is small so you need more time to get your face done, but its smallness is also good for difficult areas. It doesn't give me instant full coverage like my EDM kabuki, I have to apply many layers with the 109 to get a similar effect.
