If you go to urgent care, you most likely won't get a physician. 9/10 visits are urgent care you only see a PA or NP and they can't even really do much. Urgent care seems to also provide really poor results--every time I've gone it's a long wait, the workers seem over-stressed, you barely get any time with the doctor, and usually they just do a strep test or give you a Zithromax pack and hope you'll go away.
Anecdote that isn't remotely data: I went to an urgent care facility the first time I had a migraine aura without headache. I described it to the receptionist as a "visual hallucination", since it was a flashing checkerboard pattern that obviously wasn't real. The receptionist _ran_ to the back to get a doctor.

I had no idea what the impact would be to my insurance so I went along with it. At the hospital ER they hooked me up to IV immediately and then said I needed a spinal tap to check for meningitis because they couldn't explain the fever. I asked to leave, but nobody came to unhook me from the IV or bring my belongings back. They then guided me to another room after an hour or so with 5 people in it. I asked to leave immediately, and they said I could have a life threatening case and I needed to sign a waiver if I left. Apparently they were bringing another doctor from another hospital as emergency to do the test. This time I called my family for advice and signed the form but they were very pushy. The headache and fever were gone the next day. This experience has scarred me from going to U.S. healthcare to this day.
