Well, the jury's back............cross-hatching is proving to be my least favorite thing to do...at least with ballpoint. If I have to do this much cross-hatching to fill in a subject, I prefer digital.
As mentioned in a previous post, one doesn't have to worry about ink pooling resulting in ink blobs working digital. You don't have to worry about constantly wiping the point on tissue which I find is disruptive in workflow. One can set the opacity rather than totally relying on pressure holding a pen. With the Apple pencil, you can use both to your advantage. And due to the fact you don't have to rely on pressure, it's easier on the hand.
Not sure I will actually produce a portrait using cross-hatching as it would probably take me days versus hours to complete but that might change. In comparing the two below, I do like the results of the pepper worked in Procreate but not sure I have THAT much patience to work something as complex as a portrait. We shall see. I do admit that this can be therapeutic....very relaxing (if not having to constantly worry about blobs).
Just for fun, I took my original and added color blending mode layers to produce the following.
