I have both..I love sephora's rounded crease brush #13 coz it is more like the mac 226 which was released in the BBR collection,but slightly bigger,its a pointy,dense but fluffier than 226,you can use the tip for precise e/s application or use the sides of the brush for blending the e/s for air brushed look..macs 224,is large and fluffy,only meant for blending out e/s not for precise application. plus the difference in price mac 224 is 28 $ and sephora's is 16 $..Hope this helped
