I disagree with blatanville - To my taste the light green but not lime green UI is lovely - I prefer minimalist 2d UIs like this - so I use Valhalla stuff and a lot of Ableton's own FX -
I also disagree about unintuitive modulation - I found modulation pretty obvious - Actually all controls were pretty obvious.
I used a few tutorials bundled with the plugin at the very start and skim reading them was enough to set me in the right direction.
I never use presets, so I have (in the last 2 days) made about 20 presets that really work for my music. I got it for $49. I didn't have a granular FX of any note, so it filled a gap in my 'arsenal'.
