This is a very sophisticated application which requires a good deal of effort to set up and operate. The use of levels (foundation, ground floor, etc) can be a little annoying if you put items in and forget which level you are in because you may not be able to edit them (putting a shrub under the driveway, e.g.)
There is a good plant library, but you can't search it (only alphabetically, not by climate zone, e.g.) and you can't keep it open while you work on the landscaping.
Moving and resizing plants is easy enough, but if they are behind a larger item, say a tree, it's very hard to select/edit.
The look and feel of the program is good, but for my smaller landscaping projects, I think I could have saved some money and gone with something simpler/cheaper.
