Your choice would seem to be to go with the one that agrees with the view you already have. It doesn't matter that "my" version (It's not MY version.) was written by someone who was there, and Donald's version written in 1996, without footnotes judging from the sample pages at Amazon. I find it odd that it doesn't seem to bother you that Donald added details to the story which make Lincoln seem more heroic, and omitted mention of details which would reflect negatively on Lincoln's character.
The fact that you think that there is a genuine choice as to which is more likely to be an accurate depiction of what really happened, sort of disqualifies your comments from serious consideration on these sorts of threads.
