I think comparisons are fine in terms of technical ability, so you can weigh up which one would be best to get. e.g

'IA has a nice natural voice for [genre] but I found Miki easier for [genre]'

It at least has the portential to be useful. However...

Saying one Vocaloid is similar to another; or a mix of two different Vocaloids is deeply annoying. They may have similarities, but when a new Vocaloid is released I don't want to know that 'OMG its Luka and Len's lovechild!!!'

To be honest, I am more interested in the differences. No Vocaloid's are carbon copies of each other, if one reminds you vaguely of another chances are no one else is likely to be interested. Its whether they have improvements, new features or new combinations of strengths that matter.
