Which System Proficiency, Defense or Pace & Space (MyLeague)

Which System Proficiency Do You Like Better For A Simulated Season In MyLeague (30 Teams, Season 1, All-Time NBA Draft), Defense or Pace & Space?

For me, both of these systems are 5 stars and full bars for all 5 of my starters. So I'm trying to pick one of the two, and I need your help.

My coach is Amethyst Terry Stotts, and below is what my team looks like. The first 5 are my starters from PG-C.

Jerry West
Sidney Moncrief
Kawhi Leonard
Dave Cowens
Bill Walton
Dave Bing
Cliff Hagan
Elton Brand
Mel Daniels
Bill Sharman
Chet Walker
Rudy Tomjanovich
Bill Laimbeer
Michael Cooper

So what do you think I should use, Pace and Space or Defense?

i would always recommend using Triangle as this Features the least Attribute decreases. and besides artificial Attribute boosts/decreases the System Proficiency does exactly nothing.

Well keep in mind that I will not be playing the games myself, so these are all simulated. The Triangle is not a 5 star match for me, while Defense and Pace & Space are. I believe the star rating is important when games are simulated, correct?
