Comparing the majors I have experience with:

Computer Science was by far the hardest, if we're talking about just completing the major and graduating. There are many reasons why, but the most obvious is that it simply takes way more hours of work to complete a lab than it takes to write a paper. Then again, even the C students had no trouble finding a job related to their field.

Physics classes are a little more siloed. You basically need to collect a minor in Mathematics along the way (even more so than Computer Science), but a bad semester in Thermal Physics isn't going to mess you up in Electrodynamics. However, if you want to go on to do anything in Physics after graduation, you have to be at the very top of your class. This is not the case with careers related to Computer Science or Business.

Business Administration was a highly-impacted major at my school, and the subject material was brain-dead easy. As a result, the grading curve was actually incredibly brutal. I had one lower division weed-out class where missing 3 points total (across the entire semester, with a huge number of multiple choice questions on exams and a few papers) would drop you from an A to a B. But once you got past the lower-division filter, it was smooth sailing.
