Some of the facts are listed below to help you understand which one is better in taking admission.

1. SGSITS has its brand name. No one even knows about the institute about IET-DAVV; generally, the students who are staying outside of Madhya Pradesh.
2. There are not enough differences in the syllabus of these two institutes. And for this reason, you have to study yourself to perform better.
3. If you want to pursue higher studies, then seats are limited in the good colleges for instrumentation. For this reason, the candidate number is also less. Thus, you have a preference to alter your stream for higher studies. One of my friends has told me that many people studied very hard and appeared in GATE although they have studied opted EI in B.Tech.
4. If you are looking for placement, then DAVV is the best. This institute always has better placement statistics than the other one that is SGSITS. My friend also told me that in DAVV, most of the students from E&TC, despite EI, are preferred by the recruitment companies.

In the following, the placement statistics of these two institutes are highlighted.

If you have not so many ideas about the stream and do not aware of the institutional tag; then it is better to choose E&TC in DAVV. Besides, if you are considering these two institutes, then both are quite similar in terms of academics. However, E&TC also has many other fields in the future, so that the job opportunity might be expanded. Hence, it will be best to go for E&TC over EI.
