I am not sure what you mean by "better". References and values are
different. If you store references, you're able to manipulate the
original objects through the nodes of your tree. If you store the
values, the connection to the original object is severed, so you do
not have the leverage to change the original object, but should the
original object be destroyed, the node still contains valid data,
and not a reference pointing to nowhere.
