Many places, especially high acuity places don’t put interns in the PICU. Frankly, that seems dangerous.
As to your other point, they are all fine programs. That being said, I didn’t go to a big program for residency, and I turned out okay (…at least that’s what my mom tells me). It’s far more what you make out of it as opposed to what is handed to you.
Of those, the ones that have the most academically oriented fellowships would be Stanford, UCSF and Utah, though that also doesn’t usually matter to most trainees for some reason.
