Which is better: IIT Gandhinagar, other new IIT electrical, or BITS Pilani electrical and electronics?

You should first consider the branch and then look at the college that you want to go to. Go through the brochures, as well as whatever information is available on the website, that will provide details about the course structure. This will help you gain a brief idea about what you can expect in the next four years of your academic life, and if it suits you.

Half your battle is conquered if you have an interest in what you are studying. College rankings, average packages, and statistics will not help you much other than provide a brief overview regarding the college.

Comparison:

• New IITs have a lot of catching up to do initially. You will see that a lot of them will have a temporary campus, and some might not even have a hostel. A few students are also of the opinion that the labs are not that well developed and equipped. But, if you are going after the IIT Brand name, you should go ahead.
• BITS Pilani though is well established. There is academic flexibility, choices between electives and clubs as well. All this will ensure that you get an all-around education. Many would say that BITS Pilani is at the same level as any other IIT and better than any new IIT for sure. And if you are planning for electrical and electronics as your major, the institute is ideal. It boasts of the best faculty for electronics in Asia. A disadvantage is that BITS hikes its fee every year. It does not have any less of a brand value than IIT. But with the current fee of INR 4.23 lakhs for the first year and a 15% hike in tuition, it could get expensive.

Do your research and see which college suits you better, fees and course-wise. Then make a decision.
