I guess it depends on who you ask. From the bilingual people I've spoken too, complex languages like Chinese and English sound weirder in Vocaloid than phonetically simple langauges like Spanish and Japanese. It would make sense considering the more complicated the building blocks of a language, the harder it would be to replicate accurately.
