85mm or 135mm focal length

Black and white photo of a young blonde model stood in front of some book shelves.

I am currently on the look out for a new portrait lens. I am torn between the Nikkor 85mm f/1.2 and the Nikkor 135mm f/1.8.

I can see use cases for both, but it’s likely the 85mm would see the most use. At the Photoshop today I’ll be trying both out to see what I think.
