In terms of readability, my experience is 5E > > 2E/Basic > 1E/3E > 4E. 3E and 1E have very different strengths and weaknesses in writing style, but it's about a wash for me. All of the non-4E books I've tried have at least been fun to read, and through that of use outside of their Edition. 4E material is not useful for anything other than playing 4E, Gygax's polearm charts are evergreen.Also, I found 4e a much easier read than 3e. And don’t get me started on Gary’s writing.
