Act2 of the Kagamine's came with its own problems, basically its like a typical update; "take old bugs out, put new ones in". To me, V2 Append is about as good as the Kagamines got. The v4x feels like lazy re-hash. And lets not get started on their English - especially Len. ¬_¬

The Kagamne's biggest asset is their suppose to be a "2 for 1" deal. But Rin is often the more focused on vocal and Len an afterthought. Furthermore while the deal was good in V2, in v4 with the vocals split, you are basically getting 2 half-CFM-vocaloids instead of two full ones.

but to me, the whole "V4x" thing has been so far a lazy disappointment compared to CFM's v3 effort. Luka has basically 3 vocals and their repeated to make 6. The Kagamines' vocals lack the content of luka in the meanwhile.
