I had a feeling that this was the case. My feeling about such variations is that they are, to borrow a phrase from the lawyers, a distinction without a difference.They would all be variants on a theme. Some people work with currents flowing into the node, some with currents flowing out. Some put all the terms on one side and some put the terms with unknowns on one side and knowns on the other.
