user9229: If the game had played between to GM which game progresses to more steps if pgn notion tends more defensive approach with less blunders.
Just for recap
Scandinavian defense ECO B01
[fen ""]
1. e4 d5

Dutch defense ECO A80
[fen ""]
1.d4 f5

Both openings are quite unbalancing. Which opening would lead to a longer game, and why would this be so?

user11629: I am still not sure whether this answers your question, but: Scandinavian tends to lead to more open/tactical games while the Dutch tends to lead to more closed/positional games. If you want to profile openings I suggest to take a database and check game positions of master players around move 10-15 and see whether you like any of those positions.
But anyway (and this is not meant to be condescending; I know I wrote this before to one of your other questions): if you want to improve in chess forget about all those openings for the time being and focus on not losing pieces in one move. This will give you much better chess than if you learn some opening lines by heart, without understanding the ideas behind the openings. As a second step, learn some general principles (good, bad pieces, development, ...) At move 16 both players blundered their queen and worrying about opening theory at this level is-to be honest-a waste of time.
