Coinbase remains a highly centralized option, which won't appeal to every user. In fact their limited range of fiat gateways makes it an option which excludes the majority of users around the world. I can see where they're going with this, and they will probably end up with a banking licence in most jurisdictions soon - good for reassuring institutional investors, but hardly in tune with the original libertarian transparent cryptocurrency ethos.
I am convinced decentralized exchanges are the future, and am most excited about Local Coin Swap, launching this summer - still time to get in on their ICO if you hurry https://www.localcoinswap.com/?utm_source=bsx30
