No there isn’t more work in GS. Orthopods are some of the most blue collar workers I know, although that is a trait that I personally think is similar across all surgical specialties. It is true there is a good amount of medicine in general surgery, as a lot of them are primary on their patients throughout the hospital stay (although some people have IM cover while inpatient).
Both have a wide range of what life post training is like. Both have the ability to customize to what you want if you are flexible with location and salary.
