DeepOnion, Solaris and PriVCY are staking great.  DeepOnion is cutting their POS rewards in half but even at 5% its a good staking option imo.  PriVCY is staking at a solid 10% and its an up-and-coming privacy coin that is in its infancy.  Solaris is a sleeping giant with a small community and dev team but the devs have proven themselves to be capable of really making something great.
