I don't own any newer bags, but I have a vintage bag that is about 20 years old. The finish on the lamb needs to be redone, but the leather, seams, and structure are in excellent condition.
Also, I do check out the bags at the boutique and have become friendly with an SA who admired my vintage piece, and he shared (quietly) he used to work for LV, and Ferragamo small leather goods (I was loving a wallet) hold up much better than LV as he sees a lot fewer returns/exchanges, very few he said.
That's about all I know on quality. I love the leathers, seasonal colors, and classic lines. Took me a long time to discover that I prefer something more classic (I know, slow learner), but I do. And the variety of sizes and looks...just lovely.
