As much hate as ripple gets, I think it has the most real world applicable use among those coins.
I agree to this, it has already got a number of associations made with leading banks and this is a confirmation of the fact that it will always be in circulation. Other coins are growing just based on speculation but the people behind ripple are doing real work.
Also, we should observe that the current price for Ripple is just $0.5, it is an absolute bargain at this prices. Some people count giving coins to banks in discount as demerit but it it required to boost growth initially.
