I have the C*rescendo machine and love the features. The WF has different feet options; open toe, SITD, couching, and the 1/4 inch guide. Laser light and the needle move features are helpful. Button hole foot and button foot work well. It is one of my go-to machines.
The Aria is right below with the same features without the laser light.
You can save your favorite stitches to a memory pocket too.
You will need the XXL tutto bag for it to fit in if you want to load from the top of the bag.
