It's true that you can have too much of a good thing...please no more different editions!
THEATRICAL CUT - was the best version of any of the "cuts" it was the most cleanly edited and it had the best soundtrack out of the three. It is clear after seeing all the versions of the film that they tested all of the jokes and the ones included were cherry picked, and the best were picked to be included in this one.
SUPER DUPER CUT/EXTENDED - this was supposed to be an extended version of the film but it was actually a different cut...what I mean by that is that they changed the soundtrack and they cut out what I considered to be some of the funniest jokes from the theatrical cut and replaced them. They ALSO added some additional footage to the film after making those changes. This version of the film feels darker and less funny to me personally so I prefer the theatrical cut over it.
ONCE UPON A DEADPOOL/PG13 - This is the edition that nobody asked for and is the most unnecessary. From an editing standpoint this version of film is very sloppy, and seems like one giant montage. They don't even start this version of the film out at the beginning it jumps right into the "safe room scene". A lot of the footage included in this edition was already available on the home releases and online (apart from the short amount filmed with Fred Savage). The movie would end up edited on TV regardless of this edition existing or not. So in reality there was no need for this edition to exist apart from making more money.
