Oh yes....much more. I have programmed professionally for both, and the programming is in some ways much easier on Linux. In others, it is less easy, but also far less prone to random errors. And library management (shared objects, dll's, assemblies, pick your poison) is a LOT better. From a system administrator point of view, there is no contest for me at all. If I can make it run on Linux, it does. 1 Linux admin can handle many servers. 1 Windows admin can effectively manage only a few, due to all of the high clicky GUI overhead requirements to administrate.
