While both can be used for fundraising, they still have significant differences. Fundraising on Ethereum is more decentralized, while fundraising on the Binance platform is no doubt purely centralized. I'm pretty sure some people still prefer the former than the latter.
Along with that, take note that ICOs isn't the only thing that Ethereum is trying to do.
From that position, I do agree that decentralized system still working for ETH fundraising as you don't need to provide personal information just to acquire investment even you'll going to invest higher amount of money from the project that you are going to support, and yes there's also working product that eth is trying to provide aside from catering new ICO's tokens.
Can't say that binance can be called as ETH of 2017, they've got different approaches and different supporters.
