Great thought-provoking post - to your point, they're two different cryptos trying to serve different purposes. I ultimately am more bullish on Ethereum because it has higher application usage for consumer businesses. Microsoft, for example, is looking into a decentralized ID based off Ethereum. Wide-scale commercial applications can take crypto to the next level.

I don't love how slow or buggy ETH remains as a platform though so for anyone investing in Ethereum, I'd suggest also hedging with EOS and other alt coins.
