I strongly dislike that spelling because I find it too complicated and that is why I would rate it low. However, I would rate
Susannah higher. This is the spelling I like the most (even though I'm most used to
Susanna, the Swedish spelling). I used to dislike it because
Susanna is a rather common name among women here and that maked it boring and "dated" (as for using it for a child).
Susannah Rosemary would be really nice.
