Gauffre - Leather or Nylon?

Given the choice I'd go with the nylon hands-down- but if you live in a rainy climate and want to save a little money, the nylon would make an equally viable option.
 
Leather if money is not a problem of course. But if you can get good deals on nylon bags that are on sale, why not? I love my nylon gauffre and will get another if I find another great deal. hehe...
