xkill (assuming GUI and not headless/remote)
xkill lets you click on any X application, at which point it will close the X server connection. In most cases the client application will self-terminate at the loss of the X connection. It's wonderfully straightforward.
True, xkill is super easy to use. Who needs a task manager, if you can just click on the program you want to close.
