I would pick the LV. My reasoning though is a little different. I used to buy Gucci all the time, 25 years ago, and I still have the classic gucci doctor bag in Navy and in brown with the stripe and they still look gorgeous. The problem I have with Gucci now is that the quality doesn't seem to be the same as they used to. Ever since they had all their difficulty with tax evasion and criminal stuff, and the brothers were fighting, it just seems like things have changed. I bought a Gucci about three years ago, and it's faded now, stitching is wearing, it's just not anywhere near the same quality as LV. My LVs that are the same age are still gorgeous; I don't wear the Gucci because it looks worn, despite not wearing it nearly as much. I do like Gucci boots (the riding ones), but I just don't buy their bags anymore. I do like the style of the one you're looking at though.
I do agree with the previous poster about them not holding their value. I wouldn't purchase a Gucci unless I got it from the outlet or second-hand because it would break my heart to hear it went down $400-$500 more the next season.
An LV saleya, if you decided you didn't like it a year later, you could probably sell it for only a $100 or $200 less than what you paid. Holds it's value much more.
