From L to R: 08 Shine, 412 Pearl, 399 Pearl
I was very disappointed in 08 Shine. It applied all patchy and was just too sparkley, it was a real mess on my eye. I've used it 4-5 times and it still did not give me the results I wanted. I think I will try it wet, maybe that will solve the issues but using it dry it just did not work out for me.
I really liked 412, it has just the right amount of pigmentation and finish for a highlighter.
I know I have a MAC shade like 399, I just can't think of the name. A little too dark for an actual highlight but I liked it above the crease.
Although these are very similar, I still really like them both for highlighting.
