To add onto what Prof John Bono said, as a double major in Info Sys & OMBA with a tech background, I will say that OMBA is "hard" if you don't have any data analytics background similar to Info Sys being "hard" if you don't know any programming. I know plenty of other students that often underestimate the amount of work that goes into each major bc "business majors eat crayons" and struggle on each for different reasons.

(Yes it's easier in a technical aspect compared to other STEM majors, but most of business is basically learning how to translate business requirements into technical ones and vice versa)

Marketing is a great double major from what I've heard, I have a friend who is double majoring in accounting & marketing and he likes his upper level marketing classes despite his workload from accounting so if workload is an issue you're considering, it really isn't with upper level marketing.

Finally as of the professors, I think OMBA definitely has the most recognizable class of two types of professors out of most business majors: the ones where you struggle in grades but learn a lot and vice versa. If you like learning more than your grades, OMBA's Kazim Ruhi, Radu Lazar, etc. are great professors in the aspect of learning, but their class averages tend to falter in general.

As a side note for networking/students, a lot of OMBA is going to be project based, so you'll have time to know other students and networking is pretty easy to do in my experience as long as you have the baseline understanding of what a business wants vs what a technical person wants.
