Usually the volume of deals is higher in Mumbai compared to other T1 cities as the number of transactions are large in numbers. But it is very firm/team specific. For example, TT&A, Saraf & Partners, Luthra & JSA has better gen corp work in Delhi as compared to their Mumbai offices. At the same time, you would also find some rainmaking partners at Delhi of the other T1s such as SAM, Trilegal etc. who bring lots big deals and do heavy gen corp work.
