If we're focusing on Apple technology, we'd be remiss in not mentioning the Pages app. It's pretty well suited to fiction-writing — more elegant than Word, though lacking some of the specialized tools found in Scrivener. (I don't really consider Ulysses a good choice for novelists; I think it's better suited to cranking out shorter pieces to be published on the web.)

One compelling factor in favor of Pages is that it's deeply integrated into the Apple ecosystem, saving and storing documents by default in iCloud, so you can work seamlessly between any combination of devices. In a pinch, you can even use a borrowed computer to work on your manuscript via the iCloud web interface — no desktop app required.

To a great extent, choosing a writing tool is a highly individual matter, a question of touch and feel and aesthetics. Fans of Apple design in general may feel, as I do, that Pages is more fun and functional than the alternatives, making it a bit more appealing to sit for hours typing words onto a screen.
