Thinking of moving to Kerala

Machanmare! I’m a Malayali from Bangalore living in Bombay working in a remote capacity for a tech company here. Living in tier 1 cities is getting worse and unliveable with growing traffic, extremely poor infrastructure, and high pollution levels. We intend to continue working remote. Therefore we are contemplating a move to a different city that is not Tier 1. How is Kochi or Thrissur to live in permanently?
