Got my 16" three days ago and upgrading from the maxed out late 2013 15". I understand that some are more and some less sensitive to the issues. If I hadn't read about this, I surely wouldn't have noticed anything and it doesn't bother me at all.
When scrolling text, I don't notice anything that bothers me, even when looking for the issue.
Here is a comparison of the ufo test filmed with iPhone slow motion:
late 13 15":
16":
Both have some ghosting but the 16" has clearly more.
Now that I amused to the 16", the 15" seems a bit glossy and the image and text not as crisp to me, so in actually use, I definitely prefer the 16".
