If this is a one time project, neither are worth it.
Depends. I used the Go bird die to put birds in and around a tree panel. It made a nice big wall hanging. I entered it in quilt show and it won 1st place in it's category. I got a new Janome Jem sewing machine as prize. It was certainly worth using the die only once. I entered the quilt in the quilt auction thinking I'd make another but haven't.
