I'm not exactly sure which rankings you looked at when posting this, but according to this as of today HUMC is #1 and Morristown #2:

Morristown is a fantastic hospital though. I did my surgery rotation there and absolutely loved it, I actually felt a little spoiled being allowed to be in such a nice place (and it gives students a meal card!)
I think you've made it clear which school you're biased towards, so that point is taken. But you have no clinical medical school experience to back up your assertions. Do you have any statistics or an article on this blunt trauma statement? I tried to look this up for a while and can't find anything. Maybe a 4th year at RWJMS may chime in soon to let us all in on the scoop. As for clinical years, it's not really about living in the same city as your main hospital, firstly as you're going to be many different places for your rotations and secondly because as you said other towns are probably nicer (and safer) to be in. Many students however live in 180 (dorms) next to the hospital/school for first and second year. People realize that most of newark is a "dump", but they dont go to NJMS hoping to soak up the scenery of a beautiful city - they go there for a good medical education.
Couple things - you're correct on the US News & World Report rankings. I was going off a different ranking that is completed not by the public - but by NJ physicians every year by Castle Connolly Medical Ltd. In that ranking, Morristown is #1 and I believe Hackensack is #2. Polls are just polls and either way, both hospitals (not neccesarily the residency programs though) are very strong in my opinion. In addition, while I am just starting school next week, I do in fact have some clinical experience. Been here in the ER at Morristown for - coming up this winter on 11 years as an EMT/Tech, specifically part of the Trauma Team. From my trauma experience, my interactions with our team, discussions with those who trained at both UH & RWJ - the penetrating/blunt differentiation is pretty clear. Here at Morristown, my best approximation is about 85/15 blunt/trauma and from my colleagues that I have spoken to, RWJ in New Brunswick is much closer to that number than what you'll see at UH or St. Joe's. You will get significantly more penetrating injuries in Paterson, Newark, Jersey City, etc. and it doesn't take a rocket scientist to know why. Again, plenty of friends (MDs, Nurses, Paramedics) that work in all three of those cities and the stories are outrageous. In my opinion though, that's a big plus for a place like UH over Morristown/RWJ. As you said, most students don't choose schools based on the city itself, but rather the medical education.
As I said in my previous post, I would have been ecstatic to have gotten accepted at either NJMS or RWJ - good luck to those applying!
