Basically Wells' & Taylor's Oxford copy text, with paratext written by scholars famous for their work within the ambit of the New Historicism.
Given that Taylor was influenced by the cultural materialism of the BCCCS, this edition isn't too much of a departure from the Oxford. Still, the New Historicism is kinda annoying sometimes. Remedies the only defect of the Oxford by including play-specific commentary and notes.
I highly recommend this single volume compilation of the complete works of Shakespeare. All of the plays, sonnets, and poems are neatly presented, making them less intimidating to a new reader of Shakespeare, and user-friendly in general. Of course it's huge (about 3,500 pages), but it includes much in addition to Shakespeare's works. There are explanations of all archaic or ambiguous language (words, phrases, references) which are neatly presented in the margins and footnotes. Anything and everything that could be "Greek" to the modern reader is explained. ("'If then you do not like him... surely you are in some manifest danger not to understand him.'") This is all done aesthetically, allowing for gentle continuity of perusal; whether you choose to read them or not, they're not disruptive or annoying. There is a seventy-four page general introduction by the chief editor (one of a team six professors), the scholar Stephen Greenblatt, which is engaging and highly educational. This is followed by a general textual introduction; there's a preface and several intros in all. Additionally there are introductions, or analytical essays, that preface each play (or piece). These can be spoilers to the first time reader, but at times they provide a necessary heads-up explanation of what's to come, without which the "uninitiated" might be lost. For convenience there's even three tables of contents: traditional (in order of appearance, which, as presented, is believed by scholars to be the chronological order in which Shakespeare wrote them), by genre, and by publication date. Most importantly, all of Shakespeare's brilliant work is all here in one book. Accompaniment with its comprehensive educational content makes this book invaluable.
Whether or not you believe that one man named William Shakespeare wrote these plays, it cannot be denied that they are greatly enjoyable on their own and have influenced countless other works of art throughout the ages.
The best Norton by far. The digital version enhances the physical volume and provides any student or Shakespeare enthusiast the tools to delve further into Shakespeare's work and world than any other edition.
