Hey aspirant,
As I can't suggest you that for which branch you should go as it's totally dependent upon you because of course you won't want to waste your 4 years studying subjects in which you are not at all interested.
I can just tell you about the placement statistics of IIIT gwalior and NIT Surat
in iiit gwalior the highest package offered is 38-40lpa and the average offered is 6-7 lpa.
Whereas, in NIT SURAT the highest package offered is 29.5LPA and the average is 6-10lpa.
Hope it helps.
Good luck.
