I use the Veritas gauge and whilst I like it a lot, there are times you cannot beat a traditional pin-style gauge. I think you need one of each. It can be hard to see the wheeled gauged line when marking with the grain in some woods, but it excellent when going cross-grain.
Also, the wheel gauges have a single-sided bevel which means sometimes your bevel side is the wrong side of the line. For example, when marking for a saw cut knife wall or dovetails. Pins work better here I think.
