I haven't played with either of them much, but they seem to take two fundamentally different narrative approaches. Inform is primarily simulation driven: You describe a world model. Every user input translates into some action that affects the world, and the world changing produces relevant output. Ink is primarily narrative driven: You write the text as a branching story, with a set of explicit options for each branching point. Variables can be read and changed arbitrarily, but have no meaning other than how the narrative uses them.
