I have a few friends at both SGSITS and IET-DAVV. Based on what I heard about the institutes through them, I will say there is no comparison between IP at SGSITS and IET-DAVV. EI is superior as a branch. It has better placements, scopes, and curriculum.
EI stands for Electronics and Instrumentation. It is similar to Electronics and Telecommunication (ETC) and also has a similar syllabus with 4-5 different subjects. While IP, i.e. Industrial Production is a sub-branch of Mechanical Engineering.
According to the recent placement highlights the average CTC offered at SGSITS and IET DAVV are 5.2 LPA and 6 LPA.
If you don’t have any particular interest in a branch, then choosing EI will be better. EI offers better future prospects.
