I say surgery's the worst for a few reasons, one the other are terrible. Most of the old surgeons in this hospital are already divorced, you have to come in at the crack of dawn and work till late at night. I've been in surgeries that were over 10 hours man

The second reason is surgeons are ass holes, now I know I'm painting with a wide brush but surgeons by and large and mean and egotistical. They love yelling at people and tearing them to shreds, I actually almost failed my surgery rotation because my chief resident was such an ass and he hated my guts. I'm pretty sure he was a racist as well.
Probably the biggest reason I'd be against surgery though is number 2, my old classmate went to Howard med school and is now an ortho (super competitive) resident, he had a co-resident who was also black who got kicked out of the program and I asked him why, he said they made his co-resident hate his life until he made mistakes and they could fire him. He says they tried to do the same to him but he was able to keep it together. in general people in medicine are less jerks and nicer all around, I'm going into PM&R which also has a good work life balance to boot
