PA is better than MD/DO in specific situations.
Every freshman in undergrad should be looking at becoming a MD at a established school. I don't care if you think "the schooling is too much". Trust me, if you aim for what I am saying, you will thank me later. Why do you think every Asian tiger parent wants his kid to succeed. They have seen millionaire docs living the good life lmao. That means aim for high GPA, 510 + MCAT. If you get that, you have chances at high paying specialties (ortho, derm, optho, urology, gen surg etc.) where at most places means you're making 500k+ if not easily breaking 1m+.
Let's say you don't have that drive, and are okay with matching a DO school, well in that case you have to think about your debt burden. If it's going to be less than 300k I still think DO is worth. This would likely mean your parents help pay your rent/food etc. If it's going to be higher, I would say go PA. This is because you're likely looking at IM + fellowship, FM, neurology, psychiatry etc. If you're a hardcore worker, you can match competitive specialties, it'll just be exponentially harder than getting in a reputable MD program.
Let's say you're one of these people : "Eh, I think being a doctor is okay, but being a PA is just so much shorter schooling and I wouldn't have a debt burden, and I don't care i'm not a doctor as long as i work in healthcare", then sure also become a PA. Then the question should naturally become PA or RN to CRNA/NP. I would probably do CRNA in that situation, but that requires bedside nursing which is toxic so idk.
The significant differences is that as a PA you will have patients that want to "see the doctor", and you have to be okay with that, and not let that affect your ego (which I know for a fact affects some peoples). Second is pay. Going to a MD program will open your doors to insanely high paying fields that if you were to be a PA and work in it you would make way less. I know general surgeons making 1 mil + whose PA is maybe? breaking 200k. Another one is the stress. as a PA/NP of say a cardiology service, something goes wrong, they coming after the 700k+ cardiologist, not your measly 150k.
