I like the style of signature bag better but I do not like those colors together. In fact, I personally really hate the pink stripe. It looks out of place in that bag with the brown colors. If they uncovered the Coach tag with it's burst of pink, I'd get it a little more but unless you dress it up with pink fobs or scarf, it's just not pretty but it could be with the right accessories if you want a cute purse.
I'm not a duffle or hobo person but I have seen the duffle in person and it's a beautiful bag. I really like the tassels and this is a beautiful color that you've picked.
Bottom line from me is the first bag is very cute but I would have to spruce it a bit to make the colors work for my tastes and the duffle is just pure class. It just depends on what look you're going for. Good Luck!
