That's totally fair. I actually ended up in a sub-discipline of signal processing (I'm this guy >>16683324 if you have any good Geometric measure or probability theory using GMT recs), so I'm probably quite biased towards it being more useful. I will say, having studied linear systems and control during my 3rd year of undergrad made my senior year complex analysis course a lot easier (aside from the habit of using j for the imaginary unit vector). I was definitely more used to working with functions of complex variables than my math major classmates.
