Physician's Forumula Shimmer Strips: Bobbi Brown Dupe?

 I'm really digging Physician's Formula Shimmer Strips Bronzers. I was looking at them last week, and I had the strangest "de ja vu"  feeling I've seen them before... Well, that's because they look A LOT like Bobbi Brown's Shimmer Bricks. I'm not doing a color comparison, because they're pretty different. One, I use Bobbi Brown's as more of a highlighter where as the PF is a bronzer. They both contain five strips of color and are the same size.

Don't they look like they could be sistahs?!

I feel like the PF Shimmer Strips are actually easier to get color from than BB's. Plus, they're about $13 a pop, instead of $38. PF has more of sheen to it, whereas BB is more shimmery. My favorite Shimmer strip is Waikiki, because the top color is a peachy one, and I can double it as a glowy blush.

Have you guys tried either? Yay or nay?
