I use larch for my fence. What's good about it is that it's tough and doesn't react much to water and moisture. So it's one of the best choices for places that get a lot of rainfall.
I have not had any issues with larch, but my brother did. He said that the larch he used in his yard lost resin after some time, so he had to re-finish (apply a protective coating) after a few years. I don't know if this is an issue with all larch though because I did not have this problem.
