I think the general UTAU problem is the metallic noise and the hard, muffled sound. Although, I might say that UTAU has very little nasally-tone problem compared to VOCALOID as some UTAU VBs tend to be too sharp at some point.

Language wise (for Japanese), I think the words of UTAU is easier to decipher than VOCALOID. Usually even without too much aid of lyrics, you can somehow understand what they are saying. Ofc, this would heavily depend on the VB quality.

Overall, UTAU can only sound really good with the help of external programs which would involve large sum of post-processing. I'm not an UTAU user but these are based on my observations of some songs which seem nearly impossible to achieve with the UTAU program alone :P
