Its obviously upto you whom ever you want to choose. But i would suggest you to do the calc right - for igot you are applying 3% and unocoin 1% ?
Transparency? I just cannot see what you are talking about. We have disclosed our fee structure though a footer link on every page on unocoin
And I would like to mention, in igot they have credit system, you need to send funds first, they will credit funds in your account then you can buy bitcoins. (It can take upto 1-2 days)
In unocoin you just need to place order and send funds, you'll get bitcoins in 1-2 hours maximum. (My personal experiance with unocoin is very good
)Igot have too many limitations for new users.
