Instead of thinking along the lines of a specific specialty and a PA, think more along the lines of if you want to go to medical school or PA school. This is a decision that I recently wrestled with for two years, as I was accepted into a 5-year BS/PA program. I spent a year in the program and I learned a lot about the PA profession. I decided it wasn't for me.
This is something that you'll probably figure out after your first year of undergrad and working in the healthcare setting. For me, the answer became obvious. If you want leadership, teaching opportunities, career advancement, higher pay, more "prestige" and want to do research, go to med school! If you want medicine to be more than just a job, go to med school. If you want to spend an ample amount of time at home and don't care about most of the pro's of going to med school, go to PA school.
There are huge pros and cons of both PA school and med school. Big the one where the pros are things you think are awesome and where the alternative has the most deal-breakers. The best advice I can give you is that being a PA is not a good replacement for being a physician.
