I honestly don't think your experience will differ all that much... but even though I am still scribing, I'll give you a little anecdote
I was originally hired last year as a scribe for an outpatient family practice. For the most part I would see pretty simple cases such as follow ups, ankle sprains, runny noses, etc etc. Occasionally you'll get someone who walks in with chest pain and is having a heart attack, but unfortunately we have to send them to the ER for workup so we never see the whole case in that regard.
After working for a few months in FP, my boss asked me to go out and help train/staff/work a new level 1 trama center he was setting up. So I went out there and did about a month+ish of work there. Obviously being a trauma there were obviously more exciting cases (i.e. MVA's, strokes, drunks, gun shot wounds, etc etc), so that was a definite plus, but after a few shifts it all became more or less the same. There would be occasionally be something new and different, but at some point all the MVAs started to mix together and seem the same. Once they had someone promoted to manage the site I was offered the opportunity to either stay or go back to my FP. I chose the latter, despite the interesting cases, and greater net income I would have received in the ER.
There were two reasons I chose going back to the FP. 1) the way the schedules were set up with set times for patients, I was able to get to know the physicians very very well. I've got to know them on a personal level and I've been able to ask them questions about patients and medical school, etc. Working in the ER, most of the physicians were always busy (with good reason of course), but it was rare to ever get to speak to them about the patient cases or ask questions when I was unsure of things. I'm not sure if anyone has had different experiences in the ER, but that was mine. 2) I personally want to go into primary care, so I thought it would be a good opportunity to be exposed to the specialty I was most interested in. Even though this may change in the future, it's definitely been good to be exposed to what I
think I want to do for the rest of my life. So my advice would be to ask yourself how much you value getting to personally know your physicians, and to also keep in mind what you're interested in since it appears like you have many options!
