For about 18 mos we took my son to St. Chris and only left to go to CHOP to follow his doctors there about 14 years ago. It's impossible for me to know what St. Chris is like now, but the thing we have always missed the most is how warm and friendly everyone there is, from the biggest doc to the janitors. That especially makes a difference when you are in patient. CHOP is a huge, urban teaching hospital with all that implies, both good and bad.
We know all the doctors , some for almost 17 years. You get to know all of them through in-patient stays mainly. Ditto for the fellows. We've always been impressed with their knowledge, responsiveness and commitment; it's a top program and they get the cream of the crop. The nurse practitioners are excellent and very experienced too.
There is a high level of consistency in the treatment plans from one dr to the next and they seem to communicate/consult with each other quite a bit, so in some instances you are getting the benefit of the group brain.
Have we had frustrations and disagreements over the years? Ha, you bet. No place is perfect. CHOP is huge, with many cracks to fall through, so you have to be alert and proactive and not afraid to speak up (politely!)
Having a consult is a great idea!
Good luck with your decision.
