I can only comment on one of these programs, but I imagine that with averaging, they are all pretty similar. One of the strengths of all of these programs is that you work hard. You will have long days, and you will have relatively shorter ones. I averaged in the high 60s/low 70s at my program. Some of my co-residents averaged lower as well as higher and that just depends on variations in rotations and case loads.
The majority of my main OR months, the work was loaded up during the week. We had night float coverage which removed call during the week. We then covered 1-2 weekend days a month, leaving 2 full free weekends.
Your daily life is going to be busy during residency. It should be that way for every resident. A more important thing to explore is that you find a city where you want to live and a program with people and training opportunities that fit your goals. Otherwise, you could be working 45 hours a week and still hate it.
