Modinagar

Hello Antra,
Both institutes mentioned by you are equally good and thus it will be very difficult to tell which one will be the best option.
However, we can help you with the parameters that you can keep in mind while choosing an institute among the three.
You can consider the below parameters
1) Faculty,
2) Affiliation / Recognition
3) Course Material,
4) Quality Education,
5) Fees
6) Infrastructure
7) Success Rate.
8) Placement
9) Top recruiting companies.
Also, if possible go through the alumni speak section to get an idea what the alumni thinks about the college.
All the best.

You should go for Galgotias, it ranks 43 in top 50 private colleges in India.

Hello Dear,
Go for Chennai campus.
Also, here is a tool called college comparison app by Shiksha. You can compare any of two colleges. Here is the link:

Both are good college but you should try to get admission in SRM University. For better information and comparison between the colleges please check the link and compare these colleges:

SRM is best option then CGC Landran as it is SRM so it gives better faculties better placement record and strong alumni record as compared to CGC Landran

Comparison is the key here.
If you have no other choice, go for it.
SRM, Modinagar is not the best university in India. If you choose to stay local, it's your choice. There are good alternatives. Do not settle for less.
All the best!
