Are cs branch at lower nits better then private colleges such as Srm Vit etc.
See if you are in top NIT's like NIT WARANGAL, TRICHY etc then yeah! the scope you will get in lower branches like Industrial Engineering etc, can be better than the average packages offered in SRM/VIT.
But if you want to say in a broader aspect then firstly you should focus on the subject matter. See there are no so called lower and upper, every branch have its own advantage or disadvantage. But in subjects like CSE/IT the employability is much higher than other branches as the user base is growing every day. Thus I would say if you can go for CSE it would be the best, that is in any college or university. And frankly speaking if you go for VIT then if you are a good student then you will be able to get a job package much greater than you expect in so called lower branches of NIT's.
Now everything is dependent on your thought and if you agree with my facts then only go for it else choose your own best possible path decided by you.
I hope this answer helps. All the very best for your future endeavors!
