Which is the best tier 2 city to settle down in India?

Considering the fact that almost all toer 1 cities have become densely populated and uninhabitable due to pollution, traffic, pricing etc. which tier 2 cities are the best options to settle? Most common response I heard is Jaipur, Pune, Indore, Cochi. Any other cities you think can be better than them? What are your thoughts? Where do you live and where do you want to move?
