NGP and BZA are both central (heart) to Indian Railways; for that matter, every town/city matters. I don't see a reason to compare beyond their geographical and other allied factors, which don't have much relevance here. Also, if such a discussion for passing time is allowed, then someone will come up with other cities as well, which will only clog the forum. Long Live IR!, for IR to live long both NGP and BZA are important.
