Although many might not agree, I think ECE is much better than electrical engineering. People tend to choose IID mainly because of the brand name that comes attached to it. If the tag was to be negated, then by all terms IIT Roorkee is better than IIT Delhi’s Electrical Engineering.
Moreover, I feel Electrical has too much workload both in IIT Delhi as well as Roorkee. This does not save you time for extracurricular activities.
Delhi is one of the most polluted cities in India and does affect the overall educational experience of the students. Although my personal suggestion is to opt for IIT Roorkee ECE, it’s better to talk to students from both institutes and branches.
