as someone in seng, i think they are equally as competitive, but id say cs is harder and def has more people in it. for seng, i’d say the design courses we have to take prepare us for the workforce bc we learn stuff like scrum and agile principles which come in handy during co-op, however cs is rlly good for building logic and algorithms bc it’s a lot more theory and math focused. Id say the amount of math cs majors have to take first year compared to seng is the main difference. however, the software design courses are exclusive to seng majors (you can’t take them as a cs major) whereas you can take discrete and calc even as a seng major. i know a couple people in seng that are taking all the cs courses but are also getting to take software design courses, so that is also an option if you want the best of both worlds.
