Cutting the doors

Hi All,
I'm about ready to cut my doors out and wonder if anyone has used this zip bit attached to the router with good results or shoud I stick with a jigsaw.
I'll cut my outside door panels first from my outside wall, then glue up my inside walls then cut those door panels out and build the doors
