The raw sound that comes out of this synth is just brilliant. I make shoegaze/dreampop, and the pads in particular sound so warm, full and just plain awesome! The effects sound fine, although I tend to use other effects if I'm to be honest. They are certainly not bad though, I just tend to have quite specific tastes with FX.
Worth bearing in mind that it can be a pretty resource hungry synth, but if you are after that vintage analog sound, u-he have nailed it - you really can't go wrong with this synth. Highly recommended.
