I'm an Essie girl (should say I *was* an Essie girl when I lived stateside, not so easy to get here in NZ). OPI are good, the brush is a bit wonky for french though (I don't use the brush with the bottle, I use a smaller brush I have for this purpose - I have two, one for working with white L&P and another for the white polish). China Glaze isn't bad, but they have gone gloopy on me.
Good luck!
Nancy
