User blog comment:Angel Emfrbl/Vocaloid Vs UTAU/@comment-5051846-20130117194208

I think the difficulty in defining whether the best UTAU can beat Vocaloid comes from the differing levels of skill in producers. A producer could make a Vocaloid original with bad tuning that an UTAU under a good user does a better cover of, leading people to justify their opinion that UTAU can do better than Vocaloid. In some ways, it proves it. But it leaves it subjective enough to cause arguement.

It also depends on what people are looking for. If you don't like an electronic overtone, then you are pretty much out of the target audience for UTAU. But sometimes the undulations of an UTAU may sound more realistic and add emotion to a song, even if the sound produced has the robotic twang.
