I have several shapers both big and small, and I love them. That being said, if I had to choose between shaper and mill, I would take the mill. But unless you live in a small apartment, there's no reason to choose. And if you do live in a small apartment, you should think about getting rid of something so that you have room for both. The bigest advantage that the shaper has is that it uses cheap tools that are easy to sharpen. I think about that every time I break a $50 end mill.
