I think the black distressed with snakeskin trim. I have a patent Riki and although I love it to death and it is my favorite bag, I wear it just about every single day (even though I've bought a few more bags since) because I know that 1) the patent trend is not going to last forever and 2) I just can't wear patent leather when it's hot out and that will be very soon. I live in Sacramento so it's hot here much of the year.
I think the distressed leather is more timeless. You will be able to get more use out if it in the long run. I do have to say the black patent Ramona is gorgeous though! Either way you can't go wrong!
