I've been or lived in every city on the list but Memphis--and Camden, NJ. I've never had any issues in any of them but I can say that I like Chicago the least. I know there are nice areas and have seen some of them, but I just had the worst vibe there. The bad areas felt like post-war zones for 50+ years without much spark. While I haven't been to Detroit recently, I liked Greektown and being near Windsor which was a very clean city.
No doubt the older the city, the more run down the areas tended to be. There are bad areas of Miami but they haven't been bad for very long and hurricanes have a way of helping clean things up a bit. I didn't mind Cleveland, except it was July and cold.
