Naked 2?

During my home visit in Sheboygan, I decided to stop by Ulta. Of course, I came across the Naked 2 and totally tempting to buy one. I'm debating if I really want to get it since the colors are similar to the first one. However, I've been reading a lot of reviews on it and so far it seem like everyone love it! So, for those who have the Naked 2, please let me know if it's worth it? And, if there's any major different between the two! I don't want to through away another $50 if it's not much of a difference.
