Here are four different peaches for you, they're all vastly different but are all four the best peach I've seen from their respective brands. I love all four, some more than others. Hopefully this helps someone out.
Index to pinkie: China Glaze Peachy Keen, Essie Van D'Go, Barielle Blossom, OPI Back to the Beach Peach
China Glaze Peachy Keen - This is the creamiest pastel of the bunch. It's also the most opaque and has the most orange of all four.
Essie Van D'Go - This one's a lot lighter and a lot pinker when you put it up against the others.
Barielle Blossom - I love the little bit of jelly in this finish, it applies the easiest after the ChG and the color is the perfect mix of orange and pink.
OPI Back to the Beach Peach - This was my favorite peach until the other three came out recently. Now I'm looking, it doesn't really seem peach at all, does it?
