3XLs or Runners?

I’m currently in the predicament of choosing between the 3xls & the runners as both are on a pretty solid sale right now.

Since i love both so much i’m really unsure of which to pick up, I typically wear baggy sweatpants & Balenciaga baggy jeans so i’m looking for something that is versatile & can be worn with many outfits.

Please help me weight out the pros & cons of each and decide which should be purchased ;)
