Yukari is among the top 15 vocaloids so is pretty popular, a lot of it is owed to the joint popularity of her voiceroid and vocaloid. Definitely isn't underused.

Sweet Ann I find is a voice who can be sexual and innocent due to its tone, it has the advantage in the upper range of being a bit ethereal and lower more mature. Very few vocaloids have the ability to convey both an idea and a counter idea in the same voicebank. Even though its not intentional, Sweet Ann is the "all round" vocal of the Engloids, able to fulfill a variety of roles and a shame many think the box art is ugly (Lena Horne isn't ugly guys!). If there was ever evidence that people will base their opinions on a boxart, Sweet Ann is the most notable.
