Reaming a neck mearly removes material and does nothing to improve neck wall consistency. A careful neck turning will reduce neck thickness as it uniforms the neck walls all the way around.
Neither process will improve concentricity but a turned neck that is fired in a properly cut chamber will give you a good start.

I have asked this question on a couple of boards including benchrest.com.
So far no one has recommended reaming case necks.
I have inside neck reamers.
My best shooting cases to date started off being inside reamed before outside turning.
I found that the inside of the case necks were not uniform at all.
On fired cases, the reamer did not take off a lot of material, but it did engage.
I outside neck turned after reaming them.
The material that was removed might have been from the dies I was using since the expander ball was kind of hard to pull through.
I don't use those dies any more. No more expander balls.
Not sure if it was the infamous donut that I removed or not.
The 100 - 200 yard benchrest guys didn't seem to like the question.
They shoot tiny one hole groups without reaming the inside.
Just wanted to share this because I have asked the question before myself.
