I usually use a mixed ratio of Hope with my deck. Two normal and one upgraded, or vice versa, depending on whichever you favor. I find that the choices presented can be helpful, as having one less normal Hope in your deck is very, very, unlikely to make a difference (it would only make a difference if you're short exactly one Light Quantum and you have your upgraded Hope and neither of your other two and you're either going to die or lose your quanta next turn), whereas throwing in an upgraded version could save you once in a slightly greater while. In most cases, when you draw two Hopes, you'd be presented with a choice, which is always good. By having both versions in your deck, you can also gain the benefit of both worlds: get the cheap one out quickly and when you have more light quanta, replace it with the upgraded version.
