Indian cryptocurrency exchanges. Which is better?

I made an account on Koinex and it is still under review after 4 days.
On the other hand Coindelta made my account available for trading in under an hour.

Coindelta have 2FA authentication available and two more cryptocurrency to trade: OMG and QTUM.

In trade volume, Koinex wins clearly, Coindelta is still new and needs more users to increase it's trade volume.

Also rates on Koinex are much cheaper than Coindelta which obviously makes Koinex the better choice for now if you are able to wait for 8-10 days for account review as per the info from Hive account@shaikhajwad .

Comment with your suggestions for any other Indian crypto exchanges that are better or worse.
