I spent a good chunk of my life in that area on the Iowa side.
If choosing anywhere to live in Iowa, I would suggest Eldridge, Pleasant Valley, or Bettendorf.
However, if I was working in Moline, I would probably choose the Illinois side. Not because the time to make the trip from those Iowa cities is that long, but I swear that 1 of those bridges (80, 74, Arsenal, or the other one that I don't remember) is always getting worked on, and bridge traffic can be a problem.
However, that is my memory on the subject. It might be completely wrong, but worth asking about if you get the opportunity.
