They're for different roles. Well, Olaf can jungle, but he's usually used top lane. But nocturne is almost always used in jungle only.

However if you're looking for a good champion to make use of APen runes, then Olaf is the way to go. He has an AD steroid and an AS steroid, so Arpen marks/quints work the best for him.
