Best long term cryptos to buy before 2018

There are hundreds of cryptos that get comments or stories written up every day. Lets get some comments going on cryptos with solid long-term potential. The best ones besides Bitcoin, Ether, and Litecoin I've heard are:

Neo (pretty main-stream at this point)
Golem
Siacoin
Aragon

Make the comments 3 sentences or less so we can go do our own research if it seems worth-while.
