Hey priyashi,

As I have researched a lot on both of these colleges so according to me I guess you should go for NIET greater noida over GNIOT as because of the following points:-

1) faculty-the faculties are more helpful and skilled in niet than gniot.

2) crowd-the crowd of people are better in niet compared to gniot.

3) placement-the placement of niet is far better than gniot as the highest package offered in niet is 25 lpa and morever it is growing each and every year and the average package offered to cse is 4-5lpa.whereas in gniot the highest is around 10-12lpa and average is around 3lpa for cse.

Hope it helps.

Good luck.
