Those are all top programs. In the end you'll have to go with your gut feeling and priorities because reputation and career-wise I don't think you can go wrong with any of them. I'm not sure anything you hear on these forums will help you at this point since you've already visited those programs yourself.
That being said, I can tell you about my priorities but I don't know yours. Of your list, I interviewed at Cinci, Pitt, and CHLA. I thought all were fantastic programs with awesome people. As a Californian living in the Midwest for med school, I'm ready to go home and that's why CHLA stands out to me. If I didn't mind sticking it out in Ohio longer, Cinci would be higher on my list compared to Pitt, because the weather and winter driving are more daunting to this lame Californian, but reputation-wise and program-wise both Cinci and Pitt seemed to be awesome.
Can't comment on Seattle or CHOP firsthand. All of my school graduates who are interns at CHOP say they are happy and amazed by the smart people they work with, but it sounds like reputation does play a factor in them being there. The interns at UW I talked to were super happy. The one downside anybody mentioned about Seattle was rain. Long story short, this is definitely one of those "go with your gut" moments. Good luck with your rank list.
