Most of the times there is no difference. Differences arises whenever the funds have regular dividend payouts. In such cases, income tax is levied on the dividend return, so the fund value is lesser than its growth counterpart.
It is not income tax that is levied (else you would be eligible for TDS against it), it is DDT or Dividend Dist, Tax before payout that is levied there by making the tax liability NIL on the Dividend rec'd.
@Shivam DUbey the cumulative DDT+surcharge+cess (& any other tax) is roughly 30% which makes it ideal for ppl who are already in the 30% IT Bracket bcos it doesn't make much of a difference.
If you are in a lower IT bracket, might as well go for Growth and bear the Tax liability. The difference in tax will be your net gain.
