I would say EOS easy. Since they are planning on building an ecosystem with thousands of apps on board. And if you are an EOS holder you will benefit from that. They are focusing on speed, have experienced people on-board and they have all the money they need to make things happen.
Of course Bitcoin will probably always keep go up since the coins are so rare only 16 million. But as a daily mainstream use probably not so much. Ethereum I enjoy for fast transfer over to Steem so clearly it can be a good buy but I wait out now on it since it seems EOS has way more potential!
May be a little bit more complicated to setup EOS but complicated means less will do it and usually higher value for you in the long run. For the people that take the leap that will say!
