Most programs require somewhere between 60-70 hours. The prestigious programs send you near 80 (ex: Stanford, UCSF, JHU...) more often than occasionally. But like the OP, I don't care about being beaten for 3/4 years so I can pretty much get a fellowship that I can get from a A- program (ex: NWMH, UofChicago, BID....). Experience by hours is overrated because if the cases are pretty much similar, then you'll never engage your mind to handle new situations cuz you never get to read. Yet, you'll be really good at the basics.
The presence of CRNAs matters because they take the burden of boring stuff like eye cases. Some programs have less and some utilize them more. And attendings willing to step in the OR and do some cases (rare at most places). Overall, hours are better than internal medicine (except some easy consult month) so you're better off in general. University of Illinois Chicago has great hours and policies for residents. Rarely, residents are present until 5-6pm on regular days, and if you stay late on regular days, you are given hours toward more days off.
