We'd love to be able to recommend Noteshelf here, which is overall a richer notebook app (albeit one that's not quite as pretty or simple) but although it has recently added support for the Pencil, it's very basic – there's no tilt- or pressure-sensitivity.
Happily, though, Paper is easy to love. At first glance it might look like a reasonably simple drawing and diagramming tool – and on one level, for sure, that's what it is – but there are some smarts here.
They are frustratingly difficult to discover, but again it's worth poking around the support files online to understand how the apparently simple tools can be used to create graphs, org charts and Venn diagrams, can easily duplicate shapes, link shapes with lines (with optional arrows at one or both ends) and much more.
Paper doesn't demand the kind of precision you get from the Pencil, but it's certainly welcome, and the slightly, delightfully cartoonish media work great with its sensors.

Ah, Evernote. Now, this definitely isn't for everyone. For some, this uber-notebook has become an indispensable place for gathering websites, sketches, notes, to-do lists and more – the detritus of modern life as well as inspiration and creative work – but for others it's just a bit baffling and never quite clicks.
It's definitely rich and capable, though, and the ability to record audio – during a briefing meeting, say, while you sketch ideas for a client – using its simple but effective drawing tools is great (though this isn't the only app to offer that, of course). It's pleasing how the eraser tool creates nicely rounded ends to the ink strokes rather than just slicing them into sharp points.
Using the Pencil rather than a dumb stylus or your finger gives you a more expressive line since it's pressure sensitive, but more importantly the palm rejection means that you can lean your hand on the screen like you would with paper, and Evernote won't get confused and make marks where your hand is resting.

Even without a Pencil this is a handy tool for reading and annotating PDFs, Word and PowerPoint documents, and web pages. It's designed to support 'active reading', so as you're reading you can be highlighting and snipping out sections to refer to later, collapsing sections of a document down so you can refer to disparate bits of it at once, and more.
Add in the Pencil, though, and it becomes even faster to use, and it's a great example of how the Pencil's pressure- and tilt-sensitivity can be used not just to mimic real-world drawing tools.
Dragging the Pencil over text instantly selects it (rather than having to tap-and-wait with your finger), pressing harder selects any part of the document as an image, and dragging across text with the Pencil held at a flattened angle selects and highlights it. Smart.

We'll come clean: despite its assurances that it 'empowers anyone to create 3D designs easily and intuitively' we don't have the chops to produce anything remotely impressive in this 3D drawing app, but we can nevertheless see that it makes great use of the Pencil.
The idea is that you can sketch in 2D – optionally making use of smart symmetry controls – and then extrude your designs or even draw entirely in 3D space, connecting points on different planes.
Even if you're a bit clumsy and jittery, your lines are smoothed into flowing curves, and with practice we can see that it would be possible to create some elegant, organic forms at speed – and the precision of the Pencil's tip will make this whole process simpler than with any other stylus.
It might get frustrating for highly technical engineering work, but you can always use it as a tool for getting an initial concept down before exporting to IGES or OBJ files so you can work it up in other apps.
