If you are stuck trying to make your decision between the above two models, the article should help.
If you are looking for something more basic, consider the NOOK Simple Touch or the Kindle Touch.

When it comes to the "Touch" eReaders I think the biggest draw is going to be whether the purchaser has already purchased a significant amount of content from Barnes and Noble or from Amazon. If neither, then I think it is probably a draw between those two.

ZDNet explanation of Kindle library borrowing
I can't say how eager I am for Barnes and Noble to follow suit with regard to the preservation of notes. I take a lot of notes.
Visiting a store and getting your hands on a demo model, or better yet, borrowing one from a friend, will really give you an idea of the feel and functionality of a particular eReader. It's still the best way to make a decision before purchasing.
Remember, some libraries loan eReaders to their patrons to allow them to get a real feel about eReaders before making a purchase. Our local library allows patrons to checkout: Sony Reader PRS-350 Pocket Edition or B&N NOOK.
