Its because they cleaned up the vocals a lot and removed via filters a lot of the background annoyances. However, as noted from VY2's release by Bplats, if you do this you remove layers that give a convincing results, removing little bits that will often allow a vocal to sound more 3Dish rather then flat.

Cleaner results Vs natural ones? You decide which is better.

On top of this, consider also the new Vocaloid engine produces noticable differences.
