To describe VOX'd as a VSTi in it's own right, I'll quote from my Wusikstation review since it's directly applicable:

I really like the Wusikstation.
To me, Wusikstation provides a very punchy and direct sound. Most VSTi's are like looking at a styrofoam ball painted yellow, while the Wusik, as it is affectionately known, is like looking directly into the sun. OK that's a little over the top, but Wusik is very, very nice.

Lots of layers of easy to grasp programmability. More LFO's and filters and effects and whatnot than you could ever need.

Support is fast and useful on the forum.

Now I will address the VOX'd specifics. VOX'd could be called Angelic Choirs of Heaven, but that's what you expect in a synth with such a clear focus on one type of sound. There are no presets that I can say I dislike but there are a lot that are similar. There are some real gems too. The three SEQ-type patches that use the WusikEngine's wavesequencer are outstanding. The patch called Amazing Breath is truly amazing.
I've found a number of favorites and tons of great starting places, so overall I'm quite happy that I bought VOX'd.
