I think they both have their strengths honestly. The future of currency I feel will be Bitcoin or some derivation thereof. Especially when people get fed up with central banking and/or the the banks themselves fail to catch up with the technology. I think the reason so many investment firms "feel good" about Ethereum is the fact that smart contracts are a potential major cost saver for both internal and external transactions for these firms. With ETH in its infancy and and not yet widely accepted, most of the uses for this feature are speculative until mass adoption, but the MBAs and CFAs at these firms got there for a reason - they see the potential for cost cutting, for circumventing risk, for faster movement from deal close to final liquidity, etc.
