^^^ Agreed.
As a PI, while you have more demands on your time there's a lot more flexibility as well. My current PI (MD who works on a genetic disorder) is always gone by 6-6:30pm to have dinner with his family. He does end up coming back in later sometimes, or usually works from home, but he isn't tied to the hospital/lab and unable to see his family. Same with my previous PI (MD/PhD working on development), he would fairly frequently go out of town with his kids but would take his laptop and work from the road. And my father (MD/PhD in anesthesiology but he lives abroad) would usually stop by my town on his way to or from conferences every few months, something he wouldn't be able to do without the research part of his career.
I will say that one common trait I've noticed is that physician PIs don't sleep a lot, so if you like sleeping more than 3hours a day it might not be for you, though residency might change that.
