We recommend Aesop as part of the Joshua through Malachi & Ancient Greece study, Candace. The version that is listed is a beautiful newer book, but I also have one that I picked up for 50% off at Barnes and Noble (published as a part of their Barnes & Noble Classics set).
I mainly look for substantial language (not watered down or babyish) that is still understandable for my children. The newer book I mentioned above has beautiful illustrations, but that is definitely not a necessity.
I believe there are also some versions available free online. If you Google “Aesop’s Fables” you’ll see a lot of links. You could read through a few from different sites and get a feel for how the story’s language is styled in the various retellings. That might give you a good feel for what kind of version you want to get (or just use that online version!).
Hope this helps a little. Maybe others have particular editors or translations they prefer and can post actual names to look for.
