As for Sacred Soil, you don't consider the context of when you'd use it, its 1 stack cost, nor the strong regen applied by CU.
Comparing like that, in a vacuum, without context, it's really a bad thing and gives people the idea that something is better than something else, while it's not true at all in practice.
For instance, not considering the regen on CU prevent people from thinking about the consequences of that effect, which is to allow the WHM not to cast Medica II or use a Medica instead of a Cure III.
These kind of comparisons cut so much stuff from getting the full picture that they are the worst.
