Both are great. I agree w Jahpson that if you want a shoulder bag go for the flap and if you want a hand held purse go for the kelly. Another consideration is the flap can be dressed up or down, especially with the sh. The kelly is dressier to me.
I LOVE the kelly. It's so chic. When I saw it, I was really drawn to it. BUT (there has to be one of those), I am not a handheld bag person and like my hands free. So my vote goes with the flap. It really depends on your personal preference. HEY...why not get BOTH. He!He!
