There will be a lot of this close encounters when it comes to overwhelming each other. Both coins had a great potential. Ripple has been surprisingly moving this year aside from the market conditions. While Ethereum keeps on coming back even when its declining.
Ethereum have good potential crypto currency so many peoples are think like that, But Ripple is a banking sector platform so many organization is follow the Ripple project. May be next year second quarter is possible on Ethereum beat the Ripple marketcap. I personally believe both are maintained a same level in future.
