Ripple is completely different than Bitcoin. To start with, Ripple is centralized while Bitcoin is decentralized, so banks obviously will favor Ripple. Bitcoin is more of a threat because it can't really be controlled by anyone. We've see governments trying to regulate the market and they have been unable. What Ripple is doing is that they are actually offering a service and a respective product (XRP), that product can be used by financial instituions and banks to lower their overal transactions costs, so it makes sense for banks to consider that. For Bitcoin that doesn't work, to transfer bitcoin you'll need to pay fees and the system is not nearly as efficient at Ripple's, which means that it will not be favored by banks or anyone else. Ripple is the clear winner.
