This is a great insight. It's hard to break the habit of defaulting to the node voltage method when it's been beaten into your head via practice in EE labs. In the lab I used in college, something like ~90% of the ammeters were broken or wrong (mostly due to blown fuses by other clueless undergrads), but the voltmeters were always reliable. Defaulting to the voltmeter also meant you didn't have to move things around on the breadboard. I think this hands-on experience influenced the way I approach circuits even if they are on paper or a computer screen.
