Which one should I choose: IIT Jodhpur, IIT Ropar CSE or IIT BHU Electrical?

All of these are very good IITs and all of them will give the IIT tag and the exposure you need, but I would recommend you to go for IIT BHU electrical over IIT Jodhpur or Ropar CSE.

• Electrical engineering is one of the best courses and you will also get to learn some aspects of coding from computer science courses. This is very important in today's world and can be useful if you wish to get into a computer or technology-related job in the future. 
• Electrical and Electronics students are allowed to sit at all the campus interviews of every company including noncore companies too. This is a major advantage for electrical and electronics students to appear for more interviews and get their desired job. Moreover, in the present situation of India, most of the engineers prefer noncore jobs over core companies because they receive higher salaries and more recognition from them. 
• In your fourth year, you will also have core job opportunities in the campus placement drive. According to recent placement highlights of IIT BHU, many students got placed with decent CTC at core companies. Students also performed quite well in competitive examinations like GATE. 
• Among the given choices, IIT BHU is the oldest and have all the facilities required. 

IIT BHU Electrical is definitely the better choice because of the above reasons.
