Theyre good if you want to frankenstein a stick together since i hear theyre common ground, and easier to fuck with than the standard 360 controller.
The standard xbox360 one isn't actually too bad if you can find the new revision. The dpad points are a little iffy but not horrible, and they are only $65 (ONLY! hah!)
