The actual callback function will take just as long to execute whether it's C_Timer or OnUpdate. I'm not too involved in nameplates, but I think that OnUpdate is exactly how often you need to do your stuff (eg before each frame is drawn), so there's no point in using a timer, and it would probably even be slightly worse, because you could never time it exactly according to each frame.
