I don’t have a favorite. I picked up one I have on my desk and it’s Sally Hansen Hard as Nails XTREME Wear – it’s pretty shiny and truly clear, as opposed to some that are yellowish. I also have a Broadway GEL. Just like colored polish, I find there’s little difference in any of them, from $1 up, although I’ve never paid more than around $15 for any. I have a lot of Broadway brand from the Dollar General store, and if I remember right, it’s $1.00. Have you ever gotten the high end ones? Like $30–40 a bottle? If so, did you really see a difference between it and the less expensive ones?
