While technically Ethereum's ~15tx/s is an order of magnitude more than Bitcoin's 7x max, that's not really what I had in mind, they're effectively equivalent in relation to where they need to be (hundreds or thousands/sec). And as expected Ethereum's tx cost is increasing with usage too. And Vitalik to his credit is clear that Ethereum still has significant work to do on this front:

>In a lengthy statement released to TechCrunch, Buterin explained that he plans to spend more time ensuring that Ethereum fulfills its potential as a platform.

"2017 really has been the year where hype in crypto, including financial hype and social hype in general has far exceeded the reality of what existing blockchain systems can offer. There is a lot of attention, and a lot of eager expectation, but as far as reality goes the practical usability of blockchains has in some cases even regressed due to rising transaction fees."

"I expect 2018, at least within the Ethereum space that I’m best able to speak about, will be the year of action. It will be the year where all of the ideas around scalability, Plasma, proof-of-stake, and privacy that we have painstakingly worked on and refined over the last four years are finally going to turn into real, live working code that you can play around in a highly mature form in some cases on testnets, and in some key cases even on the public mainnet. Everyone in the Ethereum space recognizes that the world is watching, and we are ready to deliver."
