First consideration, be sure the dealer gives unlimited lessons on either machine.
I have the Dream and love adding stippling to the design. You can get perfect positioning with either the camera feature or the sensor pen. The camera feature shows the design exactly on the fabric. I have quilted a baby quilt using the camera feature to line up the embroidery design.
As mentioned above the digitizing is for more simple shapes not complicated pictures. The machine will resize the design and change the stitch density for you.
I use the WF for binding and quilting bag projects. There are different feet available that go on the WF.
There is a built help feature with the press of a button.
Love the buttonhole feature and that it sews the button on for you too.
The machine saves the stitch count if you have to turn off the machine. You resume in the same place the next time.
Love the accessory box that comes with the machine filled with machine feet and tools.
I don't know the other machine you are considering so not able to help.
