Because the departments are the same, here are some details about the colleges:

1. Location: As you are aware, NITJ is located in Jalandhar, which is close to two major cities in Punjab (Amritsar & Ludhiana). As a result, connectivity is better than in Hamirpur, Himachal. Nature lovers, on the other hand, would prefer Hamirpur to Jalandhar.
2. Campus: NITJ has a 170-acre campus, whereas NIT Hamirpur has 320+ acres of lush greenery and hills surrounding it. In comparison to Jalandhar, Hamirpur has the better infrastructure (though new modern buildings are being constructed in NITJ, which boost the infrastructure of the campus in the coming few years)
3. Department: The ECE department at NITJ is located in the main block, also known as the Gool building, and the faculty is excellent and dedicated, willing to assist you at any time and out of the way if approached. When it comes to placement, it is excellent, almost on par with cs placements. The crowd in NITJ is very good, but if you don't want to miss out on nature and infrastructure, Hamirpur is always your heaven.

As a result, with a slight advantage in infrastructure and recent rankings, NIT Hamirpur would be a better choice.
