Hello aspirant

The both campuses are good both comparing with academics and placement oppurtunities.Pursuing CSE from iit Lucknow is good option bcoz the branch u are choosing is also matter since CSE is in demand and comparatively more chances and upgrades.And coming to ECE at NIT kurukshetr is also good in terms of considering the demand of ECE in core companies.

But finally i would say one thing don't blindly go on once suggestion u must have the interest and zeal to get achieved to ur goal

Hope it helps

Thank you & Good Luck!!!
