Tough decision! I have the chocolate and love it, however, also loove the glazed espresso (especially with the olive suede!) and want one myself. Sorry, I am totally no help!
Maybe you should just see which you can get a better deal on and let the price decide?
Hmm....tough choice. The chocolate looks like it has such deliciously squishy leather, but the glazed espresso's color has so much more depth. I think I'd lean more towards the espresso. I like the contrasting green suede.
Are they final sale? If not, get both and decide in person.
