^ I've had both. I'd probably recommend the Nikon 35mm because of the f1.8 aperture.
Even though the Tokina has macro ability, it isn't particularly useful since it's fairly wide. If you do get close, then what happens it that you often end up blocking light because you have to get close to it.
The Nikon 35mm is consistently good and I believe a little cheaper. If you don't think you'll need the macro the Nikon version is better.
Here's a mini pinecone I took with the Tokina 35mm.
