If I need an applique I'll draw it and use the Silhouette to cut. You can scan in. I used to freehand appliques, but the Silhouette is far better at cutting than I am with a pair of scissors. I'm not limited to whatever is popular or designers think is great.
I'm lucky that I do know how to use a good drawing program.
I do have an Accuquilt - but I'll never buy an applique die.
If you have a Sizzix, you can use any Sizzix die - even one designed for paper cutting. You are not limited to quilting dies.
