@AnatomyGrey12 is one of the few pre-DOs with his head on straight.
MD is better than DO 99% of the time.
@OrdinaryDO can say whatever he wants about anecdotal exceptions to the rule but they don't apply here. Exceptions would be if you are interested in primary care and have free tuition at a DO vs loans at an MD. Or if you have to stay in a certain geographic location due to family circumstances.
And by the way shame on everyone for not calling out
@SlugMD for saying obgyn is a surgical sub specialty. I'd be willing to bet if you surveyed 100 obgyn less than 5 would consider themselves "surgery subspecialists." Look at charting outcomes, it isn't that competitive.
OP go to the MD schools if you get in. You may want OB now but you may not in 4 years. Go to the school where more doors are open.
