China Glaze Stella vs. China Glaze Cowgirl Up

I love Stella. It´s one of my winter favorites. I always wanted to know how different from Cowgirl Up it is. Now I know it, thanks to my friend Boruvka. They are very similar, but Stella is more "clean" purple and Cowgirl Up has more red-brown undertones. Cowgirl Up is richer, deeper. I like still Stella because of its color purity. What about you? Index finger - Cowgirl Up, middle finger - Cowgirl Up, ring finger - Stella, pinky - Stella. Both colors are in 2 coats with Essie Good To Go! top coat.
