Since both the colleges are considered highly reputable and among the best in the country, you should focus on the branch. The choice of the branch directly depends on your inclinations and future goals. 

To make it easier for you I have explained each branch in short:

Electrical and Instrumentation: 

• Instrumentation engineering is the engineering specialization that focuses primarily on the principle and operation of measuring instruments that are used in the design and configuration of automated systems in electrical, pneumatic domains, etc. 
• These engineers usually work at chemical or manufacturing plants and their job role involves improving productivity, reliability, safety, optimization, and stability. 
• They are responsible for designing devices that measure physical quantities such as pressure, flow, and temperature. You will require a lot of knowledge in physics much more than electromagnetic theory. 

Electrical and Electronics:

• In this students learn to design electronic circuits, and computer systems and also develop control systems. Electronics play a key role in the implementation and control of electrical machines. 
• The course mainly focuses on designing and testing ICs, inductors, capacitors and resistors and includes fundamentals and principles of physics, mathematics, computer science, and project management. 
• The sub-disciplines of this branch are power, control, electronics, microelectronics and Signal Processing, Telecommunications, Instrumentation and Computers.

Although the choice depends on your own interests, EE has a better scope than EIE. 

Here is a detailed analysis of the aforementioned colleges based on some common aspects

• Branch: Electronics and E&TC are two very different branches covering many different subjects. So it’s best to go through the syllabus and then decide the branch of your choice.
• Academics: Academically, VIT Pune and WCE Sangli are better choices than MIT and POCT mainly because both are autonomous and have a pointer scale and thus scoring a good CGPA is easier.
• Fees: WCE charges the least among these colleges mainly because it’s a government-funded college. PICT charges fewer fees in comparison with MIT and VIT.
• Location: All three institutes namely PICT, MIT & VIT, are in Pune so enjoy great location benefits

Hope you make a wise choice!

Frankly speaking, both Electronics and Instrumentation and CSE are equally good branches that open up ample opportunities in the future. Let us have a brief comparison of the NIT Silchar, E&I, and TEZU.

Infrastructure – TEZU is leading in terms of the best infrastructure and well-equipped lab facilities, especially in the CSE branch.

Faculty – TEZU is gifted with more highly qualified and experienced faculties than others.

Placement – NITs and TEZU have had a good record of placement in recent years.

Research – CSE has an active and advanced research environment at TEZU.

Other than the qualities of the institute, your initial preference should be given to your interest in the core subject.

Both IIT Guwahati and IIT BHU are highly comparable to each other in terms of academic and professional excellence. However, both have their own unique strengths and weaknesses and my answer will guide you to make the most appropriate choice 

Course structure: The course structure of both EE at IIT BHU and ECE at IIT Guwahati is similar and has very few differences. 

Infrastructure: IIT Guwahati has better infrastructure because of its later establishment. IIT Guwahati is known for its extremely beautiful campus with rich natural beauty.

Alumni: Being older, IIT BHU has a longstanding legacy of excellence. This has a positive effect on the placements.

Culture: IIT BHU has a rich and dynamic work culture that is generally not found in engineering colleges.

Faculty and peer pool: Both IIT BHU and IIT Guwahati have excellent faculty and peer pool being reputed institutions.

Ultimately, it’s all about personal inclinations and there is no fixed right or better choice.
