Dash - clear roadmap to be a widely accepted currency for spending. Fast and cheap. Have a treasury budget to fund projects. Large team and, most importantly, they're innovative, not just copycats. And masternode shares!

Ark - Extremely ambitious goals and, so far, have delivered consistently. Bigger goals are Smartbridges (connecting different blockchains for interoperability), one-click blockchain launch (clone of Ark blockchain) and a strong public presence. They have sponsored multiple university hackathons. And DPoS!

Rise - been a rocky path recently but if they can survive they have tremendous potential. Drag and drop dapp tools, side chains, multiple languages offered, smart contracts, and the best DPoS around. (I REALLY like coins that earn me dividends)

Ethereum and NEO - because it is Ethereum and NEO

Request Network - payment requesting and invoice solutions. Integrating all forms of payments. Obviously much more than just that but worth looking into.

AdEx - advertising is big money and there are multiple advertising coins out there, this is just the one I liked the most

GenesisVision - the evolution of financial markets. Bringing exchanges, brokers and investors together. Integration of crypto, traditional stocks and banks to bring investing of all mediums together

There are more but these are my biggest
