On Editing the "Three" Hamlets

"There are three printed versions of Hamlet:


- Q1 ("the Bad Quarto"), published in 1603.
- Q2 ("the Second Quarto"), published in 1604/5
- F1 ("the First Folio") published in 1623

Which of these three texts is 'correct'?
[M]ost readers would probably prefer just one version, the "original" Hamlet. They don't know that this "original" Hamlet does not exist. Some passages that we know so well can be found in Q1 or Q2 only, others only in F. Whatever version we read (or see performed) is an edited version, a conflation of these three first versions.
As an editor, one has to make choices in every line. In a critical edition the editor has to choose the version that will appear in the main text, and the other versions will then appear in small print (like footnotes) under the text. These decisions are not always easy."
