I'd strongly advise you to consider these two:

Essentia (ESS) - Essentia is a masternoded multi-chained set of protocols connecting centralized and decentralized resources to create new powerful interactions and experiences

Usechain (UST) - Introduce a brand-new consensus mechanism, and the World's First Mirror Identity Blockchain. 

Both seem very promising, have solid team behind them and a well-written whitepaper.
