Hello aspirant,

Both colleges have equal preference and approximately same cut-off.

But as far placement is concerned NIT PATNA is better.

NIT Patna provides well equipped labs for ECE department as NIT Patna is an older NIT.
In NIT Patna, placement record is excellent for ECE Department. Students from the department have been regularly recruited by public sectors and MNC companies with high package. The faculty members of NIT Patna are also great.

On the contrary, NIT AP is newer NIT so many people tries to ignore it. But it is excellent for academics as well as cultural criterion. It has well dedicated faculties. The study environment of NIT AP is awesome and technical support also very good.

The choice completely depends on you. Take the path what your heart says to you!

Good luck!
