I think personally Tezos + EOS are late to the party. Ethereum has a huge huge advantage being already in use and keep making new partners that will support the platform. They do tons of updates now soon with the coming metropolis ......
I dont see how these new platforms can even come close in say 1+ year. ETH will for sure evolve during that time as well and considering how much money they have i would say they are pretty far ahead in every way.
IT does not matter what Tezos or EOS promise, in the end of the day that is a promise on paper and its a long way from that to real product. During that time ETH and maybe other platforms will be eating up the market. One full year is a looong time in this space.
I hope the best for all 3 but my money is on ETH (right now).
As with everything we have to adapt to the market
