Examples of tree building in Maya, Zbrush, Unity

I am interested in making trees, especially when it comes to molding the leaves so I have been looking at tutorials of efficient ways to create trees in different programs. I will then create a tree and see which program seems the easiest to use for this function or whether a combination is best (also in regards to polycount etc).
