How? Both of them are offering same platform. Zerodha doesn't have even own DP which wisdom have. Moreover Wisdom's CC is superior since they have toll free No and Live chat services.
I think Wisdom is better.
I have gone through background of Zerodha, it was underdog couple of years back. So may be the Wisdom Capital today.
Whats the problem in comparisons? It makes consumers more choosy, I believe.
