Actually, this is conditional...

If you mean your entire application is not the active Window, then using a system hook is best.

If you mean that a dialog in your application has lot focus, but your application still has focus, then you should use an IMessageFilter and register it with Application.AddMessageFilter.

Using system hooks slows down the speed of the entire window manager because your program has to filter and process the necessary data. If you don't NEED to, don't do it.

Also, if you do use a system hook, make sure you unregister it before exiting your application, like in your main window's (i.e., the Form that was run with Application.Run) Close event handler, or better yet in the Dispose override, or before youe application's entry point (i.e., Main) exits.
