Proe is slightly more expensive than SW. Proe does not need a Server. It can be a node-locked license too. We are running it that way. Functionality wise, Proe is far far superior to SW or any other mid-range CAD like SE, Inventor etc. Proe is a top end product. We are on WF5.... on the way to Creo 1.0. Waiting for Creo 1.0 to stabilize.
