How do routers compare to laser engraving machines?

Taking an over-simplified look on a mechanical level, a router is really just a large engraving machine. The X, Y, Z and spindle seeds are similar in function. However, some router software are not as simple as some engraving software, so the user may be required to put more thought and effort into what is necessary to get the machine to produce the desired output.
