CGC Landra is a good college but we can't say the best for ECE B.Tech. There are better institutes such as Thapar University in Punjab and if you want to see for the whole of India then there are definitely much better institues such as the much coveted IITs, NITs and other GFTIs. Also many private colleges like BITs are also the top choice for most of the students. So I would like to say that there are definitely many good colleges for ECE B.Tech course not only in Punjab but also in the whole of India.
