Which is more robust, model or multi target tracking?

I'm looking to design a tracking object that is to remain stationary but able to be viewed at different angles. Which is the more robust tracking method, the use of a model target or a multi-target? My initial inclination was to design a sophisticated multi-target using a polyhedron and multiple QR codes. This looks non-trivial, however, and so the multi-target would likely be a cuboid with multiple QR codes. Would this be more or less robust than some other shape that could be tracked as a model? Thanks!
