I'm much in favor of the "flavor" of the parchment look....
Assuming we're voting on the formatting it's easily #5. The flavor text in several of the others feels kind of unnecessary, especially considering the things it's describing are things you can see.
If this were a text based adventure or d&d the extra description would be good, but ESO's environment can speak for itself.
Well.... for me the formatting - the "look" - is more important. Sorry, but I like the parchment with the "handwritten" text.
Then again, I'm not primarily interested in this sort of rewrite. I remember everything in detail, except of course for the latest content - but even the latest content takes me only one playthrough and then I remember it in detail as well. So I'm not the primary "market" for your addon, though I do give you a lot of credit for going there.
Such a pity you had 5 as the only handwritten on parchment one, since it was the text alone you wanted us to evaluate.
5 is by far the nicest looking but the text is very much lacking imo.
I think your poll is going to be distorted by people just choosing based on the appearance of the text box (especially since it looks like you didn't explain exactly what you wanted at first).
Anyway, hope these comments are helpful.
