which is considered the preferred text?

My very first post!
Please bear with me as I am inexperienced.
I recently began to read Chaucer.
Some confusion (on my part) as to which
Troilus and Cressida is considered the "better" read:
Chaucer or Shakespeare?

Have you read: "Valley of The Dolls"?
V.O.T.D. is a "ripoff" of Shakespeare's T. and C.D.
