This beast is so packed with usefulness you won't be able to absorb it all at first, theres alot of presets, and they're all very nice. I would say the highlights are the guitars (lead and bass), acoustic bass, and the strings. The pianos/keyboards are also very nice, although in some piano presets you can sometimes tell that its synthesised (but i have been playing piano since i was born).
The Drum Kits really blew me away, I was expecting that side of the product to be neglected, but no its extremely diverse and useful, makes creating beats 10,000 times easier. Only grudge i have with the sound is the brass and woodwinds, it doesn't sound as real as say the edirol orchestral. This is why i gave 'sound' a score of 9.
The onboard effects ARE good, and fairly efficient on CPU. The interface is VERY VERY VERY straightforward, one of the most easy to use VSTis. I didn't even need to peek at the manuals. This is very useful, there are 6 large knobs which change according to the instrument you are playing, this makes for JOYFULLY EASY EDITING, i'm telling you that is a really welcome feature. Eg. on elect guitars you can tweak the drive/fuzz/fret-noise/wah-speed, and on a drum kit you can adjust the filter/resonance/kick/snare level. These 6 knobs can be super quickly be assigned to a different CC#. Searching patches is a damn BREEZE too.
I feel like i'm using one of those really expensive workstations like the triton etc. but with the ease and beautiful GUI of a PC VSTi. This is a very good creation from steinberg and wizoo. They have my respect for this!
