Which city would you choose? (Pune)

So I had the luxury of spending the last 5 weeks in Pune for work and now its looking like I might be moving to India for a little over a year. I have a choice between the following:

Mumbai
Kolkata
Chennie
Bhubaneswar
Hyderabad
Pune
Punjab
Dehli

Can I get some feedback on the following? I am young so I guess a major plus would be the social/nightlife.

Thanks
