I'm a little biased toward the 1st one because I, personally, can't wear much turquoise which looks like one of the colors in the 2nd shot. The 1st colorway has no yellow - it's all creamy white, light blue and the stamp is in shades of grey/dove. I'll wear this one as a belt with jeans, as a pop of color with all black and as an accent with white.
1st one is my vote.......
