Heh, hardly any room for debate. Sidious was the stronger one by far.
It seemed like a very strange coincidence that he lost his lightsaber at that time. The perfect time, in fact, for Anakin to come in. No, he decided that should happen. Seems quite strange that he would whine about being too weak to do anything one second, and then be able to blast someone out a window with Force lightning the next.
Everything seemed far too coincidental to have happened by chance.
