The results of realism are usually more true in the professional vocaloids then the acted ones.

Miku, for example is designed to sound cute, and maintains her qualities of "cute" going up and down octaves. That means some sacrifice in other areas... Realism... Her voice is the same tone going up as down, which the human vocal doesn't do naturally. Since the voice is not suppose to be realistic, it gives it flexibility, but that flexibility often leads to more engine fill-ins.

Professional Vocaloids like Prima, Gackpoid... They sound more closer to the vocalist, but they have costs too. Their better singers since their results are more realistic and rely less on the engine to fill-in. But it can limit the flexibility within the vocal, in particular the more extreme end of professional vocaloids like Prima are almost completely bound to their styles which means their hard to break out of them. In addition, they maintain their natural tone, but other aspects of the tone suffer. They may not sound in one octave like they sound in another.

Oliver and Kagamine Len are good examples, as both represent the most extreme ends of both spectrum of vocal direction. Both are "young male" vocals, but because Len is voiced by a mature female, his voice is not "true" and reflects more on a mature female vocal then a young boys. Whereas Oliver's being voiced by a young male, is. Also Len, is not really a professional singer voice, and Oliver "is" because he is focused on choir type. :-/
