^^ This. If you want a senior capstone, engineering classes, some EE classes, and some hardware classes, definitely chose COEN. If you really like math and theoretical CS, chose the a&s program. The general sentiment is that COEN will be a bit tougher because of the very high credit hours and engineering requirements but the other CS program is definitely also rigorous. COEN sizing is limited as it’s a competitive admission major and essentially no one can transfer into it vs. CS which doesn’t have that cap. But in summary, it really comes down to whether or not you want an engineering degree or a liberal arts/science degree. In a&s you have language reqs and other liberal arts classes vs. in engineering where you spend those credit hours in engineering classes.
