The full feature list on the first tab is very informative so I can't add much to that. It delivers those features as promised.
A couple reasons for a very high rating:
One, don't be fooled by the simple looking interface. This is an extremely deep plugin. The description as a chorus/delay/reverb/ensemble is no exaggeration. Each of the 6 pages has a few knobs and each could lead you down a different experimental or tweaking perfection path.
But don't despair. The tooltips that pop up at the bottom of the plugin are helpful. Even having a good understanding of modulation and delay, this plugin took me a half-hour to fully grasp and would have taken much longer without the tooltips.
With every parameter aimed at the above functions, my impression is that the author intended to do that, but turn it up to 11. This can go from very subtle to ridiculous (in playing with it I made a whole soundscape from the sound of my guitar switch being turned on). Putting wetness to a lower percent I was enjoying having random sounding pitch trails floating around the source like a drunken choir.
Last, the promised 'parameter smoothing.' I frankly am not sure what is under the hood in terms of coding for this but the effect is noticeable. Routing this to my DAW controller and/or automating it thru the DAW, I could produce very smooth sounding pitch bends a la a tape cassette slowing down. Not that I ever had noticeable clicks with other delay plugs, but there was something a little more 'realistic' to the operation here - I think correctly described as smooth.
After installing this, I removed several other plugins from different categories.
