Universa (UTN) - Brings the best of both ETH & BTC. Making massive strides on a weekly basis in the corporate/political world, will be a top 10 coin by the 2019.

Besides that my next one would be WAVES, it just does everything right and is perfect for ANYONE to simply get started with their own token.

Lastly I gotta mention little ol ECC the coin that just keeps chuggin, not an ETH killer but will be a formidable platform in the future.
