I would like to say the tower because their the good people(heroes) in the post apocalyptic world but from a survivors stand point I would probably stick with the mallers. They're hardened criminals who aren't afraid to kill if it means protecting their own. I also could see them teaming up with the colony making their lives much safer than the average tower resident. But that being said it would be nice to meet some of my favorite people from the tower such as Riley, lizzy, and Kelly.
