My brother is pursuing MTech Mechatronics from IIT Patna. So, I have some ideas about the degree program. If you are a Robotics or Mechatronics enthusiast, you are perfect for this course. 

• The course curriculum is great. It is easy to score decent CGPA as compared to other departments.
• There are two departmental labs. One of the labs has necessary instrumentation, to carry out the course work. The other is set up by Bosch to study engine ECUs.
• Placement for this branch is average. If you are talented and work for it you can also get internship offers.
• Companies like TVS, Tata Innovation Lab visit the campus for R&D profiles.

MTech Mechatronics at IIT Patna is a decent option, you can definitely go for it.

Last year some of my friends were also caught in this dilemma and wondered the same question. It is recommended to contact seniors from the colleges you want to compare through social media. Check out each college's gymkhana and college websites to see what events they are participating in. You'll get a sense of what kind of life you'll have in the coming 4 years. 

The following table shows a brief insight of both institutes:

There is no way to find everything in one college that you desire, and there will always be advantages and disadvantages. You should make the right decision for yourself if the available facilities and atmosphere will be productive to you or not. 

Now, for the IIT BBS electrical and mechanical departments, they have separate schools with full lab facilities on a permanent campus. The majority of the professors are from IIT Kharagpur, and they are all knowledgeable and helpful to the students, given that they are all highly qualified and experts in their fields.

One of my friends studied at IIT Patna and this might be able to help you with your question. IIT Patna has better infrastructural facilities compared to IIT Jodhpur. He has been on the campus for almost 2 years and the facilities are really really good. Whereas IIT Jodhpur has recently shifted to their new campus, so it will take time for them to adjust or maintain the new setting.

IIT Patna also has 10 more seats in CSE Department than IIT Jodhpur. According to 2020 

NIRF Ranking, IIT Patna (26th rank) has performed far better than IIT Jodhpur (53rd Rank).

The following table gives a brief insight on both institutes:

If you can contact someone from IIT Jodhpur, make sure you can get a complete picture of the university. At last, both are very good colleges in India with excellent facilities and opportunities. For some, Patna is a stereotype, so don’t think in this manner as IIT Patna is a really good institute to go for.

One of my friends studies at IIT Dhanbad, and according to him the coding culture of IIT Dhanbad is developed and good. The following points are based on his experience at IIT Dhanbad:

• CSE students conduct several coding workshops and students join coding clubs, and associations year-round. 
• The institute has the Association of Computing Machinery (ACM) that organizes seminars, lectures, competitions, and presentations if you are interested in coding. 
• It also has Cyverlabs Club with different branches such as Web Development, Machine Learning, Arduino Development, etc. The club is headed by experienced seniors of IIT Dhanbad. 
• They also help and train students in gaining computing skills. 

Therefore, if you are thinking to join IIT Dhanbad then you can go for it. It has a great coding culture. Also, the institutes organize various coding events and competitions for students all around the year which helps them acquiring a good knowledge of it.
