Anastasia beverly hills VS Makeup revolution

I'm about to buy a contour palette but I can't decide which one since it's my first time to use it. I found 2 palettes on the net here in my country that offers an ABH contour powder kit for $20 used twice, bought last december, and MR for $20 used twice, bought 4 months ago. Which one should I buy? I live in japan and I can't find them in store so these are my only choices. I was actually looking for Kat von d but I'm not lucky to find them.
