I would say that overall the quality is very good but some lines are more hardy than others.
For daily use, the monogram canvas and damier are VERY hardy. My friends and I are quite hard on our wallets and bags and the LVs have stood up to the test!! bags from these lines are staples and will last for a long long time. The epi line holds up pretty well too!
For the other lines like Vernis, MiniLin, MC etc, you have to be more careful with them. Don't expose them to extreme temperatures, don't be too hard on them. FInd a patient SA and tell them what type of bag and usage you are looking for and have them explain the pros and cons of the different bags you like.
and if anything else, you can always bring it back to LV for repairs although i've heard some horror stories on the forum lately, which isn't good.
